Carlos Vela has warned Javier Hernandez that he will have to consider his future if he fails to break in to the Manchester Untied team soon.
Hernandez has started just one Premier League game under David Moyes so far this season and was an unused substitute in the 3-1 win against Fulham yesterday.
Despite his lack of playing time, the Mexican international has scored four goals for Manchester United with three coming in the Capital One Cup.
Vela, who will face Manchester United in the Champions League on Tuesday, believes Hernandez has the ability to succeed at Old Trafford but must consider leaving if he doesn't break in to the team soon.
"Javier is my good friend - and I hope he gets lots of chances this season at Manchester United," Vela, who spent seven years at Arsenal, told The People.
"He is one of the best finishers in England and deserves chances under the new coach.
"If he plays regularly he will score, so I don't totally understand why a player of his quality has not played more games.
"If he doesn't play regularly he will need to think about leaving.
"You always want to succeed at the biggest clubs - but if he is not given the chance there will be big teams in England and Europe wanting him."
Vela knows all too well how a move can change Hernandez's fortunes.
Since leaving the Gunners on a permanent basis in 2012, Vela has flourished in La Liga, scoring 14 goals for Real Sociedad last season.
In comparison, he only managed three Premier League starts for Arsenal and three goals.
Arsene Wenger remained convinced on Vela's ability, however, and made sure a buy-back clause was inserted in to the deal when he was sold to Sociedad.
