Tottenham are not worried about Manchester United's interest in Spurs midfielder Eric Dier, according to the Daily Mail.

It was reported earlier this week that United boss Jose Mourinho is lining up a £40m bid for the Englishman.

Dier signed a new five-year, £50,000 a week deal with Spurs in September, and chairman Daniel Levy has warned that there will be no further pay rises.

Levy has reassured fans in a Spurs Supporters Trust meeting that he will not be selling Tottenham's key players this summer.

The club is now preparing for a big year in the Champions League after their Premier League title hopes ended last week with a 1-0 loss to West Ham.
