Manchester United manager Sir Alex Ferguson is said to be fuming with Nani after the winger was involved in a training ground punch-up with reserve team midfielder Davide Petrucci.

The Daily Mail has reported that Nani was involved in a fracas with Petrucci at the clubs Carrington training ground and landed a blow on the young midfielder.

Nani exchanged heated words with Petrucci before the Portuguese midfielder called the youngster in to the gym and landed a blow in front of the Manchester United squad.

Players eventually broke up the situation but the Mail has stated that Ferguson was left fuming with the actions of Nani and will now decide what disciplinary actions to take.

The winger has struggled to find his best form this season and was hauled off at half-time against Liverpool last weekend after a less than impressive opening 45 minutes.

This loss of form has also come at a time when he has been negotiating a new contract with Manchester United and was strongly linked with a £25million move to Zenit St. Petersburg in the summer.

The Mail believes that Ferguson may now look to cash in on a player who refused to put pen-to-paper on a deal that would have seen him earn around £130,000-a-week at Old Trafford.

The 25-year-old missed a penalty against Galatasaray in the Champions League and has not been able to reproduce the form of last season where he impressed after the arrival of Ashley Young.

With Antonio Valencia now a regular in the first team, Nani is not always guaranteed a place and his future at the club may now be uncertain after this latest fracas.

Despite the incident Nani will start against Tottenham as Valencia has been ruled out of action with an ankle injury.
