West Ham United owner David Sullivan has taken to his son's Twitter account to clear-up comments he made about Queens Park Rangers striker Charlie Austin.

Sullivan had previously questioned Austin's long-term fitness, referencing the striker's failed medical at Hull City two seasons ago.

Sullivan attempted to clarify his comments which he believed had been take out of context.

"He is a player I greatly admire. However, he failed a medical at Hull two years ago," Sullivan said.

"Clearly an old injury left a severe doubt with the Hull medical team about the longevity of his career.

"I fully accept he is playing very well and the old injury is not impacting upon him at this moment in time."

He added: "I was simply saying at West Ham United we've been very unlucky with injuries to strikers, going right back to Dean Ashton.

"Three of our main four strikers are injured at this moment in time. So for us, with our limited budget, our bad luck over injured strikers and the fact he failed a medical at Hull would be a risk we couldn't take.

"However, I'm sure many other clubs would take a different view and I hope he plays on until he's 37 or 38 as he's clearly a super professional and a great player."
