Tottenham boss Harry Redknapp doubtful over fitness of Emmanuel Adebayor and Rafael van der Vaart ahead of Newcastle United clash

Sandro, Kranjcar and Corluka all face late fitness tests ahead of clash with Newcastle United on Sunday, as 64-year-old raises concerns over duo's hamstring problems

Tottenham manager Harry Redknapp has raised doubts over the fitness of Emmanuel Adebayor and Rafael van der Vaart ahead of Sunday’s clash with Newcastle United.

Redknapp has revealed that the Togolese international picked up a hamstring strain in the 2-1 victory over Arsenal in Spurs' last Premier League outing.

Whilst the 64-year-old is hopeful Adebayor may be fit in time for the fixture at St James’ Park, he is also cautious that a return to action to soon for the on-loan Manchester City striker could only worsen the injury.

Speaking to Sky Sports News, Redknapp said: "He has got a bit of a hamstring [problem].He played on with it last week. He did it in the first half against Arsenal and he played on, which is not easy. He did have a tear. It's touch and go for him really.

"It's a dangerous one. If he tears it badly, he has got a grade one tear if he makes a real mess of it and he could be out for six or seven weeks.

"It's a difficult one to risk him, but we will see how he feels. We will give him a couple of days yet, keep treating him and hopefully he could be okay.

"If he is a doubt, I wouldn't want to risk him. I wouldn't want to lose him long term.''

Redknapp also expressed similar concerns over Van der Vaart, who also may be sidelined with a recurring hamstring problem that was once again exasperated on international duty last week.

"He sometimes has a problem with that,'' he added. "He has had a few hamstring [injuries] since he's been with us, but he's important to us - he scores goals. He's an amazing finisher."

Tottenham’s injury woes may be compounded before the weekend’s clash with Verdan Corluka, Sandro and Niko Kranjcar all facing late fitness tests.
