Chelsea are reportedly monitoring Antoine Griezmann's situation ahead of the summer transfer window.
According to Corriere dello Sport (h/t Sport Witness' Tom Coast), Barcelona and Manchester United are the leading contenders for the Atletico Madrid striker's signature, but the Blues are "in the background," keeping an eye on developments.
The Frenchman has a €100 million buyout clause in his contract. Given Atleti will most likely accept nothing less, any prospective suitors will need to meet that clause. It should come down to Griezmann's preference and the contracts on offer should more than one club come in for him.
