Tottenham approach Juventus right-back Dani Alves amid uncertainty over Kyle Walker's future

Tottenham have opened talks with Juventus right-back Dani Alves over a summer transfer amid uncertainty over the future of Kyle Walker, according to reports.

Yahoo Sport says Spurs have proposed an initial two-year deal for the 34-year-old Brazilian with an option for a third season.

Alves has excelled in his first season in Italian football, helping Juventus win the Serie A title and qualify for the Champions League final in Cardiff, where they will face Spanish giants Real Madrid.

Manchester City manager Pep Guardiola is also reported to be interested in signing Alves, who is understood to be keen on playing in the Premier League.

"I've always said that playing in England is something I've got pending," Alves said last summer.

"I don't know when but I'd like to play there, to experience in person what I see from the sofa. The way the people live football. Wow, it's incredible. Full stadiums, living every moment."

The report comes amid doubts over the future of Walker, who is reportedly keen on improving his terms by moving to another big Premier League club.

The 26-year-old has a contract with Spurs until 2021 that is worth £70,000 ($91,000) per week.

Spurs boss Mauricio Pochettino has conceded that the club will not be able to compete with the likes of Chelsea and Manchester United in the transfer market for the very top players this summer.

"We have our targets and we will see if we can achieve them like every season," the Argentine coach was quoted as saying by the Daily Telegraph.

"We will see what happens. I don't think it's a big advantage to have qualified for the Champions League already.

"It's true when you are in a position where you are not having to play in the Champions League play-offs, it's better as you have an idea where you need to start. But I don't think it affects the targets or challenge and whether you achieve it."
