Luka Modric has paid tribute to sacked Tottenham boss Harry Redknapp.

Modric's future is now in doubt with Manchester United and Barcelona keen.

The playmaker told the Daily Star Sunday: "He had a great influence on me.

"It was very ­difficult for me in the beginning when I moved from Dinamo Zagreb to England. I needed time to adapt.

"But after two or three months, everything was okay under Harry Redknapp.

"Both he and playing in the Premier League have helped me a lot."
