Aston Villa captain Jack Grealish is at the centre of an endorsement war.

The Mirror says he is under contract with Nike and was pictured in the stands for Villa's 2-0 home defeat to Tottenham on Sunday in a white tracksuit emblazoned with their signature swoosh.

But Grealish's contract with the American brand is into its last year.

Rivals manufacturers are already circling ahead of a bidding war for the in-demand ace.

Adidas, Puma and Under Armour are all chasing Grealish's signature, as well as Nike who want the ace to renew on improved long-term terms.

Grealish's stock is expect to rise even higher this year with the star expected to make Gareth Southgate's England squad when fully fit.

Grealish, who has five caps, is also wanted by both Manchester City and Manchester United despite signing a five-year deal with boyhood club Villa last September, worth £130,000-a-week.
