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 believe 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 is signed it will raise questions over where Wayne Rooney fits into Alex Ferguson's plans, although the United manager has stated that he intends to offer the England striker a new deal.
That resolve may be tested over the summer, especially as United are not likely to offer Rooney the same terms as he signed with his last deal and if Lewandowski arrives the Pole will expect to be first-choice.
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."
Bayern are now planning to formalise efforts to tempt Suarez away from Anfield. Liverpool have insisted that the Uruguayan will not leave the club this summer, despite him being hit with a 10-game suspension for biting Chelsea defender Branislav Ivanovic.
While Suarez has told team-mates that La Liga, rather than the Bundesliga, is his preferred destination should he leave Liverpool, the impending arrival of Pep Guardiola as Bayern coach could be decisive.
Guardiola has made no secret of his admiration of Suarez, who is represented by Pere Guardiola, the former Barcelona coach's brother.
