Arsene Wenger has confirmed that Arsenal's Alexis Sanchez was substituted against Huddersfield Town due to a minor hamstring problem but expects the forward to be fit for Saturday's (2 December) clash against Manchester United.

Sanchez was on the scoresheet as Arsenal put five past the Terriers on Wednesday and extended their streak of consecutive home wins to 12 ahead of the visit of Jose Mourinho's side.

The Chile international was replaced by Danny Welbeck after 73 minutes with Wenger revealing in his post-match press conference that the change was partially enforced due to a minor knock.

Arsenal had already lost Alexandre Lacazette to injury by that point with the France international now ruled out of the visit of United, but Wenger insists he still expects Sanchez to feature against his side's old rivals.

"We have offensive weapons, you know," Wenger said while discussing his options for Saturday, the Daily Mail report.

"We have Danny Welbeck, Olivier Giroud and Jack Wilshere who all came on and they are all offensive players.

"I will see what I do for Saturday but ideally you wanted him [Lacazette] there. Everybody else looks to be okay, yes. Sanchez had a little hamstring problem and that is why I took him off but I think he will be alright."

Mourinho has frequently drawn criticism for how he has set up his teams away to potential title challengers this season, with his side drawing a blank in their visits to Liverpool and Chelsea and scoring just once in their matches away to the top five in the league.

This term, United are enjoying their best start to a campaign since the retirement of Sir Alex Ferguson in 2013 but a point at the Emirates Stadium may not be enough with Manchester City surging ahead of them at the summit of the Premier League, with the gap between the two Manchester rivals already at eight points.

Wenger dismissed suggestions that his old rival Mourinho might arrive in north London this weekend and "park the bus", insisting that United will come to attack.

"Man United is a strong team and I expect us just to cope with the problems they will give us. They will attack as well. They will not only defend," Wenger said.

"I haven't seen them a lot and it is not down to me to judge the way they play. I have just to look at the way we play and to prepare well for the game. They are a dangerous team, they have made fantastic results so to beat a team like that you need to be at your best and that's what I want to focus on."
