Bayern Munich are expected to make a move for Liverpool's Luis Suarez with the Germans increasingly resigned to missing out on Robert Lewandowski to Manchester United.
United are confident that they are now favourites to sign Lewandowski, a long-term target, who scored four goals in Borussia Dortmund's 4-1 Champions League semi-final first leg victory over Real Madrid.
If Lewandowski, 24, is signed it will raise questions over where Wayne Rooney fits into Sir Alex Ferguson's plans, although the United manager has already stated that he intends to offer the striker, who has two years left on his contract, a new deal.
That resolve may be tested over the (northern) summer, especially as United are not likely to offer Rooney, 27, the same terms as he signed with his last deal and if Lewandowski arrives he will expect to be first-choice alongside Robin van Persie.
When asked whether he could find room for Lewandowski, whose contract expires in June 2014, in his team, Ferguson said: "Have I got room for him? I can find room for anybody."
