Steven Pienaar feels Tottenham will face a new battle to keep hold of Luka Modric this summer. Modric has been key to Spurs' success after they ­resisted moves from Chelsea to take the Croatian across London.

But with Manchester United ready to make the 26-year-old a target in the summer, Pienaar, now on-loan at Everton, fears Modric will once again be tempted.

"Luka is a top player for Spurs and if he leaves it is hard to say what will ­happen there," Pienaar told the Sunday Mirror.

"He is such an important member of the team. Tottenham will want to keep him at the club, but it is difficult when a player like him wants to move on.

"As a player only a few ­opportunities to move on come up in your life, so I can see it from both sides.

"It was hard for Luka at the start of the season because he was thinking about his ­future. But he is a good ­professional and after the chance to leave Spurs passed he did everything he could for the team. He is that kind of guy.

"That's why the other players like him so much. But I understand from my own experience that if a good ­opportunity is blocked by your club, it can be hard to concentrate."
