#4 Antoine Griezmann (Atletico Madrid)
This choice must be prefaced by saying that Griezmann has been an unbelievable success since he arrived at Atletico Madrid. He's been their star, scoring 106 goals in 198 total appearances.
A move, however, has been touted for over a season now, specifically to Barcelona, and with reason. He stayed at Atletico to help them during the transfer embargo but a high probability remains that he'll move to the Camp Now for this coming season.
His style, simply, fits that team more. He's a silky dribbler, with brilliant link-up ability, and the thought of him combining with Lionel Messi, Luis Suarez, and Ousmane Dembele is frightening.
It's why he performs so well with his country, where he links superbly with players like Olivier Giroud, Dimitri Payet, and the aforementioned Dembele.
He's too small and slight to be a main forward and this is what has been lacking with Atletico; it's noticeable that Griezmann only started hitting top form this season when Diego Costa joined him in attack from January.
With that tough battler beside him, he now has 17 league goals and seems to be enjoying his football again. When Atletico dramatically won the league title in 2013/2014, a massive part of the success was down to Costa's incessant bullying and harassing of defensive lines, and when he does depart, the team's attack will be in good hands.
In this case, Griezmann's dependence on Diego Costa or any other bullying strikers simply underlines the fact that Atletico isn't the best fit for him. It may undoubtedly be an excellent club, and he may have thrived during his time at the club. However, the mere thought of him donning a Barcelona jersey is bound to send shivers down most spines.
