#6 Ousmane Dembele to Arsenal

This is highly unlikely to happen for two reasons. One, Barcelona only bought him last summer for a mammoth £135.5 million and, two, he is a highly talented player that could go on to be among the very best players of his generation.
However, the arrival of Malcom complicates things for him as he will have to fight harder in order to get minutes in a team that is filled with superstars. As a result, there is a very tiny chance that Barca could let go of him.
Currently, rumours are linking him with a move to Arsenal. The Gunners, who are being managed by a different coach for the first time in over two decades, would have to make the greatest deal of their millennium to get the Frenchman to the Emirates.
