Mexico manager Miguel Herrera has urged Javier Hernandez to leave Manchester United this summer.

Throughout his time at Old Trafford Hernandez has largely struggled to consistently impose himself on the first team but saw his role become even more marginalised during the 2013/14 campaign.

The 25-year-old was handed just six starts in the Premier League despite both Wayne Rooney and Robin van Persie's absences during United's dismal attempt to defend their title as he was overlooked at David Moyes.

Although his stellar record of 35 goals in 58 appearances for his country ensured his place in Mexico's World Cup squad came under no threat, his national team manager believes his star striker needs a change.

"In the case of 'Chicharito', I believe it'd be in his interest to leave so he is taken into consideration to play," Herrera said, Sky Sports report.

New United manager Louis van Gaal revealed earlier this week he has discussed his transfer plans with the club's chief executive Ed Woodward with his arrival likely to instigate a number of changes amongst playing personnel after the club recorded their worst ever Premier League season

It remains to be seen what role the 62-year-old has planned for Hernandez, but the striker admits he may have to consider his options following the World Cup.

"There is obviously uncertainty [regarding my future], but right now I am fully focused on the national team," Hernandez told Record.

"My agent and my staff help me work it all out.

"My future could be decided tomorrow, a little after or within three months. (I could) stay there (in Manchester), I really don't know."

Mexico get their World Cup campaign started against Cameroon on 13 June before taking on hosts Brazil on 17 June. A potential group decider against Croatia awaits on 23 June.
