Chelsea will rival any attempt by Manchester United to prise Antoine Griezmann out of Atletico Madrid in future transfer windows after watching him for the last two years.

United are monitoring Griezmann’s situation at Atletico, with Spanish reports claiming manager Diego Simeone could seek a new challenge at the end of the season.

That would put a huge question mark against the future of Griezmann, who has suggested that he will look to leave Atletico if Simeone goes.
