Tottenham Hotspur are believed to be interested in signing Valencia right-back Joao Cancelo, according to The Daily Mail.
However, they face competition from Italian giants Juventus, who want to sign the Portuguese player as a replacement for Dani Alves, while Spurs find themselves in a similar position.
They sold Kyle Walker for a deal worth around £50 million to Manchester City and are still to sign anyone this summer.
Spurs want to add another right-back to their squad alongside Kieran Trippier and youngster Kyle Walker-Peters.
They may now feel they have to step up their efforts as Trippier suffered an ankle injury during a friendly against Juventus, leaving Mauricio Pochettino short of specialists in the position.
Cancelo, 23, represented Portugal at the European Under-21 Championships, playing against Serbia, Spain and Macedonia.
He began his career at Benfica, where he also played at left-back, before switching to Valencia, where he has established himself in the first team, playing 38 matches last season.
His performances have aroused the attention of bigger clubs, and he is understood to want to leave.
Even if Cancelo does decide Tottenham is the better option at this stage of his career than Juventus, there is no guarantee the deal will happen.
The London-based club may see a £25 million price tag, as reported by the Daily Mail, as too steep – and he may demand too high a wage – but having missed out on several potential transfers already this summer, the risk of Tripper’s injury leaving them short at the back may force their hand.
However, if the Tottenham hierarchy remains committed to their policy of not rushing to sign players and not paying over the odds, they are not short of options.
Eric Dier could deputise at right-back if Pochettino does not want to risk Walker-Peters in Spurs’ Premier League opener against Newcastle United this weekend.
