Danny Simpson says former bad boy Ravel Morrison has grown up at Queens Park Rangers.

Simpson was at Manchester United at the same time as maverick midfielder Morrison, who was tipped as a future Old Trafford star until then manager Sir Alex Ferguson lost patience with his indiscipline off the field.

Morrison went on to join West Ham and enjoyed a fine start to this season, only to drop out of favour under Sam Allardyce and find himself loaned out to Rangers in February.

But the 21-year-old could be about to write himself into R's folklore by helping them to promotion back to the Premier League via Saturday's play-off final against Derby.

Full-back Simpson revealed: " I've known Ravel since he was young and obviously we've both gone our own ways, but since he's come here I've noticed a big change in him.

"He's growing up, maturing and starting to realise the potential he has got. He's one of the best young players I have seen with the ball at his feet.

"Everyone knows his ability but I think he has surprised a few people with his character and his attitude. Maybe it was good for him to move away to different clubs.

"He's looking forward to the final, it's a big occasion for him."

The Wembley showdown is also a big occasion for Simpson, who never quite made the grade at Old Trafford but racked up 137 appearances in four years at Newcastle before dropping down a division to join Rangers last summer.

The 27-year-old added: "I made my Manchester United debut as a kid and played in the Champions League for them but this will be the biggest game I have played in and if we get through it it will be the biggest achievement.

"I've never played at Wembley and I think everyone who follows football knows how big this game is, and if you get through it what it means to everyone.

"I'm trying not to think about losing and spending another year in the Championship. We are just concentrating on the job we have to do.

"The whole squad knows the task ahead of us, we are all together and we all want the same outcome so we will give 100 per cent to make sure we get Premier League football.

"I think we would be the first to admit, if we don't go up, that it will have been a disappointing season. We've got Premier League players who have played at the highest level.

"The reason I came to QPR was the because of the project to get back there, and we have got one game to go. We are all ready to go out and perform in the one game to get us back to the Premier League."
