West Ham striker Javier Hernandez has denied suggestions he has asked to leave the club.

Reports in his homeland said the 29-year-old Mexican wanted to rejoin Chivas before next year's World Cup.

The former Manchester United forward, who joined the Hammers from Bayer Leverkusen for £16m in July, said the stories were "completely false".

"I am 100% committed to helping improve the situation that we are all experiencing in West Ham," he tweeted.

Hernandez added he had not asked to leave "at any time".
