Arsenal vs. Manchester United Injury News: Arsene Wenger Reveals Decision Problems

Arsene Wenger will be without Arsenal's top scorer Alexandre Lacazette when Manchester United travels to the Emirates Stadium on Saturday due to a groin injury.

Lacazette scored after just three minutes in north London on Wednesday night to spark a 5-0 rout of newly-promoted Huddersfield Town, but the French striker watched the rest of the goals from the sideline.

At half-time he was replaced by countryman Olivier Giroud due to a problem with his groin that Wenger believes could keep him "out for a while."

"He's definitely out for [Manchester United] this weekend," Wenger said, as quoted by the BBC. "It looked like a groin injury. He could be out for a while."

Lacazette has been a regular in the Arsenal line-up since signing from Lyon in the summer for a club record £46.5 million, with Wednesday's goal taking his tally to seven for the season.

His replacement Giroud scored the second in the 68th minute, sparking a flurry of three goals in four minutes with Alexis Sanchez hitting the third and Mesut Ozil scoring the fourth.

Giroud added a fifth in the closing minutes of the game which may tempt Wenger to play the Frenchman in Lacazette's place against United on Saturday.

Jose Mourinho's team heads to the Emirates in search of three points to apply pressure to Premier League leader Manchester City. Both City and United won in midweek, meaning Pep Guardiola's team retained its eight-point cushion at the summit.

Against his old nemesis, Mourinho will be keen to end United's poor recent record at the Emirates. In May, Mourinho saw his team lose 2-0 after goals from Granit Xhaka and Danny Welbeck, while the previous year, under Louis van Gaal, Arsenal blitzed United with three goals in the opening 20 minutes.

Mourinho will be hoping his summer signing up front, Romelu Lukaku, will be able to help end that run. But Lukaku has entered into a goalscoring drought that has seen him score just once in 11 games, having hit 11 in his first 10 games for the club.

But his coach could afford to joke about the dry spell this week after beating Watford 4-2 at Vicarage Road. In a reference to reports this week that teammate Marouane Fellaini is suing his boot supplier, New Balance, for £2 million, Mourinho quipped: "I think he needs a big contract with big boots because at the moment he doesn't have a sponsor."

"He's playing with black boots, I think he needs a brand to give him the right boots and pay him the right money so he goes back to scoring."

Manchester United's visit to Arsenal is the late game on Saturday, kicking off at 5.30 p.m.
