Kieran Trippier fears he will miss the start of Tottenham Hotspur’s season as he waits to find out the full extent of the ankle injury he sustained in the club’s final pre-season friendly against Juventus.

Tottenham are waiting for swelling to go down before making a full diagnosis on Trippier’s injury, but the 26-year-old is not optimistic that he will be fit for the first Premier League game against Newcastle United on Sunday.

There remains concern that Trippier could be ruled out for a number of weeks, even though Tottenham were on Monday night hopeful that scans would not reveal a break once the swelling subsided.

Trippier’s injury increases Tottenham’s need to sign a new right-back after selling Kyle Walker to Manchester City for £50million, with Valencia’s Joao Cancelo among their targets.

Cancelo is also wanted by Juventus, although the Italian side also hold an interest in Porto’s Ricardo Pereira who Spurs held talks over earlier in the summer.

A dispute over who represents Pereira saw Tottenham cool their interest, but it could well be that the London club and Juve come to an agreement over which right-back they chase to avoid an auction on either man.

With Trippier not expecting to face Newcastle and manager Mauricio Pochettino claiming 20-year-old Kyle Walker-Peters is not ready to deputise in the Premier League then Eric Dier may have to play at right-back on Sunday.

Dier started as a right-back under Pochettino at Spurs, but has since been largely used as a midfielder or a central defender in a back three.

Manchester United failed with a bid to sign Dier this summer, with the 23-year-old’s versatility just one of the reasons Pochettino is so keen to keep him.

Bayern Munich are also bid admirers of Dier and have been linked with a move for the England international this month, but Tottenham remain adamant he will not be sold.
