(CNN) -- Arsenal manager Arsene Wenger says Manchester United 'look untouchable' as they bid to take a stranglehold on the Premier League title race at home to Fulham.
Wayne Rooney returns to the United squad as they bid to go five points clear in the Premier League title race.
England striker Wayne Rooney returns on the bench after a seven-match injury absence on Wednesday when Alex Ferguson's United are expected to go five points clear of nearest challengers Liverpool.
Wenger's Arsenal would be a massive 15 points off the pace in fifth place behind Aston Villa and Chelsea -- and fighting to finish among the Champions League places.
Croatia striker Eduardo scored twice on his return after a year out as Arsenal overwhelmed Cardiff 4-0 in Monday's FA Cup fourth-round replay win to stay on course for a Wembley final.
"We are on a very strong run at the moment and we have promised to give everything until the last day of the season but at the moment Manchester United look untouchable," admitted Wenger.
"They are 12 points ahead of us and they have a game against Fulham which they will certainly win."
United face Tottenham in the League Cup final on March 1; are also still involved in the FA Cup and like Arsenal, Liverpool and Chelsea resume Champions League action in next week's first knockout stage.
Wenger says Arsenal's "basic target" is a first four Premier League finish that will guarantee more highly-lucrative top European action next season, while Ferguson has also juggled his playing resources.
As well as Rooney -- he has finally shaken off a hamstring problem -- United recall Rio Ferdinand, Nemanja Vidic, Carlos Tevez, Michael Carrick and Dimitar Berbatov following the weekend FA Cup win at Derby.
"The plan is for Wayne Rooney to be involved tomorrow night and he will start on the bench," Ferguson told Key103.
"We have handled him in the right way. The decision not to involve him on Sunday was a good one because he was able to train and that extra day has brought him on a lot."
Goalkeeper Edwin van der Sar looks to achieve a staggering 14th consecutive Premiership clean sheet, against a side yet to win an away league game this season.
