He has publicly thanked fans for the support they gave the players on Saturday after he had appealed for their backing ahead of the West Bromwich Albion game.
“It's true to say he isn't there yet," the chairman told The Sentinel. “He knows it, we know it, but we are doing all we can to get there as quickly as possible.
“That means playing games and that is what we are doing. Clearly, if we can get him firing, we know what kind of player he can be.
“Mark's been there and knows the score. Stories are legion of strikers going through this kind of patch and it often takes just one goal, however it comes, to get a player going again.
“I'm sure we all remember him playing so well and scoring so regularly for Swansea when he was a real handful.
“So much so that Manchester City paid a huge sum (£28m) - and that was a couple of years ago before prices jumped again."
