Dele Alli is in line for a mega-money adidas boot deal that will send his global profile soaring.

Sportsmail understands the Tottenham sensation, an existing adidas athlete, is in discussions over an improved contract with the sportswear firm.

It is believed the deal could be worth in excess of £8million to Alli over a minimum of five years, which would be worth more than his current Tottenham contract.

Adidas believe Alli will be an integral part of their marketing activities in the UK and abroad in the coming years and the 20-year-old has already been selected by to play a key role in their Euro 2016 operations.

Alli will star alongside Germany World Cup winner Mesut Ozil and France star Paul Pogba in their Europe-wide poster campaign, which illustrates the rapidly growing appeal of a midfielder who was playing for MK Dons in League One just a year ago.

Alli, who only made his international debut in October, will play a key role for England at Euro 2016 and looks certain to start in their Group B opener against Russia on June 11.

The money will keep rolling in for Alli beyond the European Championship. Plans are already in place to discuss a lucrative new Tottenham contract when he returns from France, even though he signed a new five-year deal worth £25,000 a week in January.

Europe’s top clubs have been tracking the talented youngster, with mega-rich French champions Paris Saint-Germain sending scouts to watch Alli on a regular basis last season.
