United, Arsenal through after FA Cup replays

United was reliant on an early goal from England striker Wayne Rooney, playing his first game in three weeks after a knee injury, to squeeze past West Ham at Old Trafford and earn a match against Fulham. Rooney later missed a penalty.

"In the FA Cup anything can happen so we are pleased to get through," veteran United midfielder Ryan Giggs said.

Arsenal left it late to seal a deserved victory at Emirates Stadium, with Jack Wilshere capping a superb display with an 86th-minute winner to knock out a tired-looking Swansea. Second-tier Brighton, the third-round conqueror of Newcastle, is next for Arsene Wenger's team.

"He is a complete midfielder," Wenger said of Wilshere, who recently returned to action after a 14-month injury absence. "He was outstanding tonight but as a team we played well, and created chance after chance."

Chelsea was booed off by a disgruntled home crowd after another worrying home performance, although the European champions looked to be cruising after goals by Demba Ba and Eden Hazard gave them a 2-0 halftime lead at Stamford Bridge.

Substitute Rickie Lambert scored with one of his first touches and Jason Puncheon grabbed the equalizer with 15 minutes remaining, leaving third-place Chelsea 13 points behind leader United with 16 games left.

Since Benitez's controversial appointment in November, Chelsea has won just two of its seven matches at home in all competitions.

"We have to be more clinical when we have chances," Benitez said. "We have to manage the game, score the third goal and finish the game but we did not do it."

Rooney endured a tough festive period on and off the pitch, first picking up an injury in training on Christmas Day and then receiving the news on Jan. 5 that his wife's 14-year-old sister had died after a battle with a rare genetic disorder.
