Ryan Babel says only he knows Virgil Van Dijk's weakness

Fulham midfielder Ryan Babel, who will face his former club Liverpool this weekend, claims he knows Virgil Van Dijk's one weakness. Babel and Van Dijk are partners at Netherlands national team, and former Liverpool ace says no one in Premier League knows about that weakness. "Virgil has definitely developed over the past years. I think he can still improve by 30 per cent. I still feel he shows 70 per cent of what he can. He can do much more, he can be fast if he wants." Babel told The Times .
