#1 Paulo Dybala

Paulo Dybala is undeniably one of the brightest prospects in world football currently. He has scored 68 goals in three seasons for Juventus and he can only improve as time passes.
However, his strained relationship with the higher order in Turin, especially boss Massimiliano Allegri, has seen him sit out some big matches. Odds are that they would patch up their differences but the possibility of a move cannot be ruled out.
Diego Simeone reportedly had dinner with Dybala in March which sparked rumors about his move even though the manager dismissed reports. If the move were to happen, Dybala could make Atletico regular contenders for the league and the Champions League.
Juventus have said that the Argentine forward is not for sale. But they said the same thing about Paul Pogba and Arturo Vidal as well.
