Portuguese winger Nani is said to be considering his future after he failed to agree a new deal with Manchester United.

Nani knows that there is plenty of competition for places at Old Trafford as he has seen Sir Alex Ferguson sign Antonio Valencia and Ashley Young in recent seasons, while Shinji Kagawa can also play in wide positions.

The Japan international has declared that he would like to play a more central role at United but there is a growing belief that Nani may have fewer opportunities in the first team next season.

The Daily Mail has reported that Nani has been unable to agree a new contract and is now considering leaving the club after five successful seasons in Manchester.

"Nani wants to stay but is feeling a little unloved," a source told the Daily Mail. "He hasn't given up on a new contract but is upset that there hasn't been greater urgency shown by United. At the moment he is not in a great frame of mind."

At 25-years-old he is considered to be hitting his peak and there is believed to be some interest from Spanish champions Real Madrid, however, he would reportedly prefer to remain at Manchester United.

Despite no sign of a new contract he does still have two years remaining on his current deal which he signed back in 2010.

United boss Sir Alex Ferguson is never one to give in to wage demands and it could mean that Nani will have to lower his expectations in order to sign a new contract.

The Mail reports that he has asked for wages in the region of £120,000-a-week which would put him in line with some of the highest earners at the club.

Should United's hand be forced then they would certainly want to make a profit on a player who arrived for a little over £20million back in 2007 and has only improved since leaving Sporting Lisbon.
