LONDON (AP):

United States forward Clint Dempsey scored twice to give Fulham a 2-0 win over Wigan in the Premier League yesterday, and Nani scored a contentious goal in Manchester United's 2-0 victory over Tottenham.

United were leading on Nemanja Vidic's 31st-minute header when Nani had a penalty appeal turned down in the closing minutes. The Portugal winger was then seen handling the ball while lying on the turf. And while goalkeeper Heurelho Gomes lined up what he believed to be a free kick, Nani nipped in front and prodded the ball into an empty net.

The upset of the day came at Wolverhampton, with the relegation-threatened side beating Manchester City 2-1, inflicting a second successive loss on one of the league's biggest spenders. Leader Chelsea and second-placed Arsenal, profited from headed winners late in their games.

At Fulham's west London ground, Dempsey headed in a cross from Carlos Salcido in the 30th minute and added his second by meeting Chris Baird's pass for a powerful finish in the area.

Great crosses

"We wanted to get more crosses in the box and the two goals that I scored were great crosses, and without that I wouldn't have been in a position to score," Dempsey told Sky Sports. "It's always good to get the first one out of the way, another good ball in by Carlos - it's the second goal I've scored off a cross from him.

"So that was probably my best goal of the day, but the most important thing was that we got the three points and we are looking to replicate that performance in the future."

Dempsey had a chance for a hat trick in the 75th, but his shot was deflected by a defender and curled just wide of the right post.

He has five goals this season, including four in the Premier League. It was the fourth two-goal game of his career in England, following braces against Chelsea in December 2008, Manchester City in April 2009 and Blackburn in November 2009,

The win gives seventh-place Fulham 12 points from 10 games.

At Old Trafford, Nani's goal in the 84th minute was initially ruled out by referee Mark Clattenburg's assistant Simon Beck, angering the United players, but after the officials ruled that the whistle had never been blown, Gomes led the Spurs' protests.

"It's a handball, he's deliberately handled it and it should have been a booking," Spurs manager Harry Redknapp said. "Everyone has seen him do it so we think it's a free kick, it's just the referee that doesn't see it.

"You can't lie on the floor and pull the ball back just because you've got the hump, because you didn't get a penalty. It was a scandalous decision and the referee has made a mess of it all."

United captain Rio Ferdinand admitted that the ruling was tough on Spurs.

"Handball but gotta play to the whistle - harsh but true," Ferdinand tweeted minutes after the final whistle.

The win kept United five points behind leaders Chelsea. Branislav Ivanovic pounced in the 84th minute for Chelsea as the visitors came from behind to beat Blackburn.

Arsenal had been denied by a string of fine saves by West Ham goalkeeper Robert Green before Alex Song nodded in Gael Clichy's cross in the 88th against the last-place club.

At Wolverhampton, US goalkeeper Marcus Hahnemann was beaten by Emmanuel Adebayor's penalty, but the home side responded with goals from Nenad Milijas and David Edwards to beat Man City.

The US first-choice goalkeeper was also celebrating, with Tim Howard keeping a shutout as Everton beat Stoke 1-0.
