Foster Back out of Arsenal

Ben Foster may be left out of the first team for the big match against Arsenal.

Rio Ferdinand and Patrice Evra are back and look set to allow Man Utd to field an unchanged team from the first leg at Arsenal tonight.

Ferdinand trained at Carrington yesterday and came through unscathed after leaving the pitch at Old Trafford last Wednesday with a suspected cracked rib.

Sir Alex Ferguson stated his belief that Evra will shrug off a leg injury he sustained in the win over Middlesbrough and appears set to name an unchanged back four.

He has options to change the midfield and forward line, but after Ryan Giggs, Paul Scholes and Dimitar Berbatov all completed 90 minutes at the Riverside Stadium, it is likely he will opt for the freshness of Anderson, Michael Carrick and Carlos Tevez.

Darren Fletcher and Edwin van der Sar could also return in place of Park Ji-sung and Ben Foster.

The United boss knows how strong a position he could be in if his side get a goal at the Emirates Stadium, which would force Arsenal to score three to knock them out - a feat no team in Europe has achieved since the 3-0 mauling at the hands of AC Milan at this stage two years ago.
