Real Madrid and Barcelona will want Tottenham Hotspur's Dele Alli - Ossie Ardiles

Alli has excelled since arriving at Tottenham from MK Dons in 2015, securing a regular England starting spot after his astonishing breakthrough season.

And the youngster has already matched his Premier League goal tally from last season, reaching double figures already for the season.

Alli isn’t alone in impressing in the current Spurs set-up, but he’s the standout player according to Ardiles, who believes that Spain’s big two will already be targeting a move for him.

"Success breeds success, and a lot of Tottenham’s players are starting to demand interest from different clubs," Ardiles said.

For Spurs to keep hold of players like Alli they will need to start winning trophies, but Ardiles thinks that the current Tottenham team are more than capable of doing just that.

"I believe if we don't have any injuries, I don't think there is any team in England whose first XI is better than Spurs," Ardiles added. "There are some other teams who are better in terms of squads - players on the bench, where we need a little bit more.

"It's very important that we win something, last season was brilliant and we finished third, qualified for the Champions League. But we need to win something like the FA Cup, the Europa League, or of course the major trophy in the Premier League. If we win it will be a lot easier to keep everybody, but if we don't there's no reason why not. We can wait another year and all these players have long contracts as well, so hopefully they will stay with us."

Tottenham's next game is against West Bromwich Albion at White Hart Lane on Saturday.
