Belgium coach Marc Wilmots has urged Benfica ace Axel Witsel to resist interest from Manchester United and Real Madrid. The two European heavyweights are chasing Witsel's signature this week.

But Wilmots told O Jogo: "Staying at Benfica can be good for Witsel, though he is ready for the challenge of Manchester United or Real Madrid.

"It's important he continues to play regularly.

"One or two more seasons at Benfica will do no harm. It will help him develop and mature."
