Harry Redknapp admits he is worried West Ham could recall Ravel Morrison.
The England Under-21 international has been outstanding for QPR since joining them on loan last month.
He is expected to stay for the rest of the season, including the play-offs if Rangers are involved, but the Hammers do have the option of taking him back to Upton Park at 24 hours’ notice.
Rangers boss Redknapp said: “With his loan they can do that. I hope they don’t. It would be a blow. I’d hate to lose him.”
Morrison, 21, was shown the door by Manchester United and his attitude was criticised by the then Old Trafford boss Sir Alex Ferguson.
And having initially made a big impact at West Ham he fell out of favour under manager Sam Allardyce, prompting Redknapp to take him to west London.
“He’s really just got to concentrate on his football, keep his head down, work hard and play as he is at the moment,” said Redknapp.
“If he does that, he’s got the ability to be one of the best players around, there’s no doubt about that.
“He glides over the floor. When he runs it’s as if he doesn’t touch the floor, and he’s got unbelievable ability on the ball. He really is a top-class talent.
“If he progresses he could be one of the biggest stars in football, he’s got that much ability.”
