LONDON - In an electrifying Champions League performance, Arsenal striker Danny Welbeck scored a hat trick that even surprised manager Arsene Wenger.If he keeps up the form from Wednesdays win over Galatasaray, the $27 million Wenger spent to bring Welbeck from the Manchester United bench to the Arsenal front line could prove to be one of the bargains of the year.It is good that slowly he gains confidence and finishes well, Wenger said after the 4-1 win over Galatasaray. Hopefully the hat trick will help him gain confidence. It is not just his finishing because he wants to help the team. His team play is good as well, his teamwork and work-rate. I believe that, technically, he is very sound, a good passer of the ball.Welbeck can show the treble wasnt a one-off when Arsenal travels across London with its notoriously porous defence to play Chelsea. Yet, Chelseas new striker has even eclipsed the instant impact Welbeck has made. Diego Costa, who joined from Atletico Madrid for around $53 million, has scored eight goals in six league games a€” even with left thigh problems a€” to ensure Chelsea tops the fledgling standings.Weve seen it before, some strikers take months and months, but hes hit the ground running, Chelsea captain John Terry said. Without speaking a word of English he gets by and gets on great with everyone. He puts himself about but gets up and battles on, and plays with little niggles.Chelsea is six points ahead of Arsenal, which is in its familiar position of fourth.Heres a look at the pick of the other Premier League games this weekend:___LACKLUSTER LIVERPOOLWith just two wins from six league games, life at Liverpool without Luis Suarez continues to be a struggle. And Daniel Sturridge could still be sidelined on Saturday when last seasons runners-up host West Bromwich Albion. Europe has provided no respite either, with Brendan Rodgers team losing 1-0 at Basel on Wednesday in the Champions League.I thought we were too soft all over the pitch, captain Steven Gerrard said in Switzerland. I thought they wanted it more, which is very disappointing. Conceding again from a set-piece isnt good enough, so we need to get it right.___POCHETTINOS PROBLEMSWhen Mauricio Pochettino switched from Southampton to Tottenham, this wasnt how he envisaged the start to the season. Tottenham, having opened the league campaign with two wins, has now gone four matches without a victory.Southampton, despite an exodus of star players, has not imploded as bookmakers predicted with their relegation odds, but is sitting second in the league. Ronald Koemans side has won four of its opening six league fixtures heading into Sundays match at Pochettinos Tottenham.One of Pochettinos problems is striker Emmanuel Adebayor only scoring once in the league.We know always a striker maybe during some periods finds it difficult to score, but he made a lot of effort for the team, Pochettino said.__ELSEWHERE...Alan Pardew seems to be the Premier League manager under the greatest pressure, with Newcastle playing Swansea on Saturday with just three points and second from bottom.Manchester United hosts Everton on Sunday with a chance to win back-to-back matches for the first time under Louis van Gaal this season. Captain Wayne Rooney begins a three-match suspension after being sent off in last weekends 2-1 win over West Ham.Third-place Manchester City travels to Aston Villa on Saturday, which is just a point behind the champions, after another frustrating Champions League night.

Womens Shoes Australia WINSTON-SALEM, N.C. -- Former top-10 players Gael Monfils and Jurgen Melzer beat higher-ranked players Friday to advance to the Winston-Salem Open final. Monfils, the Frenchman ranked No. 43 in the world, overcame early struggles to beat 38th-ranked Alexandr Dolgopolov of the Ukraine 7-6 (11), 6-3 in the first semifinal at the Wake Forest Tennis Center. "Its very good for my confidence," said Monfils, who will play in his third tournament final of the season and his first since Nice, France, in mid-May. "Im not so happy with the way I played. I could have played better. I have to play better and be more sure of things." The 32nd-ranked Melzer, from Austria, then pulled off the biggest upset in the night match, beating American Sam Querrey -- at No. 29, the highest ranked player in the semifinals, and the crowd favourite -- 6-2, 4-6, 6-3. "Ive been serving well, and my ground strokes have been getting better from match to match," said Melzer, who also is playing in his third tournament final this season and his first since winning an ATP Challenger Tour event in Dallas in March. "After losing in the first round of my last two tournaments, if somebody would have told me I could be in the finals, I wouldve signed it." Monfils and Melzer each have four ATP tournament titles. Monfils holds a 4-0 lifetime record against Melzer, including a first-round victory in Munich in early May. "Every title means a lot," Melzer said. "Ive lost all the previous matches to him, so it will be a nice matchup tomorrow. Hopefully, I can pull it off, which would also be very good leading into the U.S. Open." Monfils -- ranked No. 7 in 2011 -- lost serve twice early and went down 4-0 in the first set to Dolgopolov. The Frenchman even received treatment on his left abdominal muscles and hip during the side exchange after the third game of the set. "I had a little pain before the match, and even during the match," said Monfils, who missed a month of action dealing with ankle and biceps injuries before playing in the final hard-court tournament before neext weeks U.ddddddddddddS. Open. "It was a bit better (after the trainer) worked on it, but I still felt it during the first set," he said. "Its not a tear, but its very tight. I just have to take care of it, and I should be fine." After the injury break, Monfils broke Dolgopolovs serve twice to force the tiebreaker and win the first set. He then added two more service breaks in the second set. "It wasnt my best finish," said Dolgopolov, a Ukrainian who was playing in his first semifinal this season. "I was in the game, but every game I didnt finish out those important points. Game by game, he came back. "I was angry at myself -- I had too many chances. When you have that in your mind, after having played three matches (in the tournament), its tough to make yourself go out and forget about it." Melzer -- ranked as high as No. 8 in 2011 -- broke Querreys serve five times, and kept him off-balance for most of the match with his ground strokes and net game. Still, Querrey fought back after losing the first set, getting a pair of service breaks en route to winning the second set. He then held serve to open the third set and grab the early advantage. "I felt like I played really well for 1 1/2 sets," said Melzer, who lost two previous matches against Querrey. "Then I kind of lost it a little bit, got a little too passive on my side and forgot about the game plan. I was lucky in the beginning of the third (set) to not get broken again. But after that, I started playing well again." Querrey nearly pulled off another service break to open the third set, putting Melzer down 15-40 in the second game. But Melzer fought back to hold serve, then broke Querreys serve the next game to take the advantage. "I didnt feel my greatest out there," Querrey said, who lost in the semifinals for the second straight year. "I played a little sloppy in the first set, then that break in the second (set) helped me regain all the momentum. If I couldve stuck that other break in the third set, maybe it couldve been different." ' ' '
