AC Milan v Man Utd
AC Milan midfielder Gennaro Gattuso will be available but defender Paolo Maldini (knee) is a possible absentee.
Both players picked up injuries in the first leg and, while Gattuso should be fit, Maldini is likely to miss out.
Manchester United duo Nemanja Vidic and Rio Ferdinand are fit after recovering from collarbone and groin injuries.
Patrice Evra is suspended but Sir Alex Ferguson says he is "nowhere near making a decision" on whether Vidic or Ferdinand, or both, should play.
Louis Saha could be on the bench, despite his recent hamstring problems, but Gary Neville misses out again.
Heinze, Cristiano Ronaldo and Paul Scholes are all one booking away from a ban that would rule them out of the final, should United progress.
Milan beat United in the semi-final of the old European Cup in both 1958 and 1969.
Man Utd (from): Van der Sar, Kuszczak, O'Shea, Fletcher, Brown, Ferdinand, Vidic, Heinze, Ronaldo, Scholes, Carrick, Giggs, Richardson, Eagles, Saha, Smith, Solskjaer, Rooney, Dong.
