The transfer window in England opened on June 14 and for the major leagues in Europe it will open on July 1.
Lionel Messi and Karim Benzema have already kicked off the window in spectacular fashion, and more of football's biggest stars could also be on the move this off-season.
Kylian Mbappe has told Paris Saint-Germain he will not sign a 12-month extension on his current contract, which is expected to spark an auction for the France striker, with Real Madrid likely to be at the head of the queue.
