West Ham captain Kevin Nolan has praised a more focused Ravel Morrison, insisting he must maintain this new approach to succeed at the club.
The former Manchester United youngster has already had his character come into question on several occasions, despite being very much in his footballing infancy.
But, after the 20-year-old netted a double in the Hammers' pre-season friendly victory over Sporting Lisbon on Monday, Nolan revealed Morrison has returned from his loan spell with Birmingham with a renewed approach, and has the potential to be a big player for Sam Allardyce's men.
"The lad has got ability," Nolan told the club's official website.
"It was all the off-field stuff and his mental attitude to the game and I think he has come back with a renewed approach.
"Speaking to Lee Clark when I've had the chance to, he said he really worked hard with him and towards the end of last season he really had him on board."
Nolan also admitted that he himself will have a key role to play in Morrison's development, and is more than happy to take the youngster under his stewardship.
"Hopefully now this will be the start of what is going to be a fantastic career for him, because as you can see he has great ability and can score goals too," Nolan added.
"I'm going to help him as much as I can this season, talking to him on the pitch and off the pitch.
"If he can get it all right, he'll be a top player for years to come."
