Fulham boss Rene Meulensteen is wary of facing his former Manchester United protégé Ravel Morrison with West Ham United today.
Meulensteen tipped the 20-year-old to make England's World Cup squad next summer.
He said: "I worked with him when he first came to the club, when he was eight or nine, so I spent many, many years with him.
"What you see in him coming to the forefront in the Premier League is that he's more than capable of playing at this level and making a difference.
"When you're good enough you're old enough: I think he's good enough."
