Manchester United are putting together a world record deal for Atletico Madrid star Antoine Griezmann.

The Independent says United boss Jose Mourinho will splash out a stunning £100million on Griezmann at the end of the season in a bid to dramatically improve his attack.

The Frenchman has long been linked with an Old Trafford switch after seeing compatriot Paul Pogba return to his old stomping ground for a world-record fee.

Atletico appear to be resigned to losing their star player and will therefore look to re-sign Diego Costa from Chelsea as his replacement.

The Spaniard is unsettled at Stamford Bridge after being offered £30m-a-year to play in China.
