West Ham United striker Enner Valencia has issued an apology after criticising the club's medical staff.

The 25-year-old recently accused doctors at Upton Park of failing to support him as he tries to recover from a knee injury.

However, the Ecuadorian has now insisted that he has the "utmost respect and confidence" in the club's medics.

"I have had a number of consultation meetings with specialists in London, accompanied by members of the club's medical staff, and they have always kept me updated me on my injury," he told West Ham's official website.

"It has been a frustrating time, but I would like to make clear that I have the utmost respect and confidence in the club's medical team and the specialists I was referred to and I would like to apologise to them and the club for any issues arising from the recent press coverage.

"I will continue to work as hard as I can with them to return to help the team as quickly as possible, and continue the good start I made to the season.

"It is not possible to put an exact date on when I might be back on the pitch, but you can be rest assured that I am motivated to get fit and score more goals for West Ham United as soon as I can."

West Ham continue their Premier League campaign on Saturday when they face Liverpool at Anfield.
