Tottenham are keen on Marseille right-back Hiroki Sakai, Sky Sports Newsunderstands.

However, Spurs have concerns about signing a player that is 29 years old.

The Japan international fits the right-back profile that manager Mauricio Pochettino is looking for, but the club are targeting younger players this summer, preferably under the age of 23.

Pochettino wants to improve both full-back positions, and the club will listen to offers for both right-backs Kieran Trippier and Serge Aurier.
