Newcastle United have made a second approach for Manchester United sensation Ravel Morrison according to the Northern Echo, amid mounting speculation the player is on borrowed time at Old Trafford.

The aforementioned source suggests the Magpies have followed up their initial £500,000 bid, as reported in Daily Mail on Thursday, with an improved offer in an effort to prise the 18-year-old away from Manchester United.

Morrison dismissed reports in Thursday's press that suggested the player had rejected Manchester United's latest offer of a contract but given the increasing interest in the midfielder from their Premier League counterparts it seems the Wythenshawe born starlet faces a hugely uncertain future at Old Trafford.

The 18-year-old is widely considered one of the finest youngsters to emerge through the Manchester United academy in a generation, but his well-documented off-field indiscretions have perhaps detracted from his obvious pedigree.

The player is out of contract at the end of the season and is therefore free to discuss potential offers from foreign clubs, but although it has been suggested that Manchester United have been thwarted in their attempts to tie the player's long-term future to Old Trafford following the rejection of a new deal, Morrison claims to the contrary.

The Manchester United prodigy said on Twitter: "No contract offer to talk about"

Morrison was responding to a report in The Sun that claimed talks with Manchester United had reached an impasse and were subsequently set to lose the midfielder at the end of the season. Whilst seemingly happy to dismiss those claims there remains an unusual hiatus between club and player in regards to extending his future at Old Trafford.

There is a suggestion that Sir Alex Ferguson and David Gill, both of whom have offered their controversial Manchester United star a huge amount of support, are reluctant to reward the youngster with a lucrative new contract because of fears it might exasperate his problems away from football.

The Guardian claims Manchester United have not been forthcoming with the offer of an extension and go as far as claiming that Morrison will almost certainly leave at the end of the season. The aforementioned Northern Echo's report of a second offer from Newcastle United certainly reflects the Manchester Evening News' claim that Sir Alex Ferguson would be willing to sell his precociously talented starlet for a fee in the region of £1 million.

A source close to the attacking youngster told the Guardian that Morrison "just wants to play" but intimates Manchester United have been disappointed at the player's progression this season.

Despite Manchester United's well-documented injury concerns and perceived midfield weakness Morrison has featured only fleetingly in their Carling Cup encounters against Aldershot and Crystal Palace.

The recent return of Paul Scholes will inevitably further inhibit Morrison's first team ambitions at Manchester United and the next few weeks will determine whether or not he has a future at Old Trafford.
