Robert Lewandowsi burst onto the world football stage after dismantling Real Madrid in the Champions League semi-final, slotting four goals past Diego Lopez to effectively end Jose Mourinho's chances of winning the European Cup during his Bernabeu tenure.
The Poland international is the hottest talent on the market right now but progress on his signing seems to be slow.
Will he leave Borussia Dortmund? If so, where will he go?
New United boss David Moyes will want to make an impression with a big signing and ensure that the instability caused by Sir Alex Ferguson's retirement will not cause the defending League champions to drop the title.
Added to this, Lewandowski and Robin van Persie are a defender's nightmare and would ensure that United could again compete for Champions League glory after a disappointing quarter-final exit to Real.
Such a move is seeming increasingly unlikely, however, with the Telegraph reporting that, as well as Bayern Munich, a move to Manchester United has been blocked by Dortmund chiefs. This transfer seems unlikely.
The Bundesliga and Champions League victors have had plenty of time to scout their man, having held a few hotly-contested matches against Dortmund this year, with Lewnadowski posing the main threat.
As such, Lewandwoski has been tipped to follow his former team-mate Mario Gotze, who will also leave Dortmund for Bayern next season. The decision will most likely lie with incoming former Barcelona manager Pep Guardiola, who is believed to hold the forward in high regard.
However, again, it is reported that the powers that be in Dortmund have vetoed such a move, not wanting to lose the star talent to their main Bundesliga rivals. Dortmund are no longer in need of financial power either, having received a £30m windfall from Bayern for Gotze.
Jose Mourinho was reported to have texted Lewandowski in the wake of his defeat to advise the Pole to join the club that he will inherit next season.
Chelsea are continuing in their hunt for a frontman to replace the ailing Fernando Torres, who is also tipped to join Barcelona this summer.
Lewandowski is known as a large, strong and powerful striker, which fits in well with Jose Mourinho's style, having previously backed Didier Drogba and now giving Romelu Lukaku a shot at first-team football. A £20m bid from the Blues is reportedly on the table to test Dortmund's resilience.
Real are also on the hunt for a strong attacking forward. Lewandowski would seem like a good match for the team but Madrid have recently reportedly been closer to signing Chelsea and Manchester City target, Edinson Cavani.
Had Mourinho stayed at the Bernabeu, the deal may have been more likely, but Real chiefs seem to favour the idea of the Uruguayan frontman joining rather than Lewandowski.
