Kenny Jackett insists Leon Clarke's best form is yet to come

Clarke is set for a stormy return against old club Coventry tomorrow and is still to convince at his hometown club after one goal in 12 games since his £750,000 move back to Wolves in January.

Head coach Jackett believes the 29-year-old will have an impact at the higher level however.

"I see him having a role next season - I think he's capable of playing in the Championship," said the boss.

"I think at times you need a big man up front and he's a good option.

"The striking department isn't an area you can be short on."

Jackett feels Clarke still has something to prove at Wolves.

"I'm sure he has," he said. "I feel there's a lot of big centre forwards who come into their own in and around the 30 mark.

"I'm thinking Rickie Lambert, Grant Holt and Steve Morison who I had at my last club, took out of non league at 26-years-old and sold him at 28-years-old for £3m into the Premier League.

"A number of big centre forwards know how to use their body, they have the experience and the calmness in front of goal that maybe they didn't when they were 21.

"I think he's in that category and I think the next few years will be his best.

"He hasn't had that many minutes on the pitch but he's been substitute a lot and there's more to come."

Jackett is confident Clarke can deal with any abuse he faces at Sixfields tomorrow.

"Anything on a personal level I'm sure he'll see as secondary and take in his stride," he said.

Meanwhile, Jackett believes unwanted Jamie O'Hara will move on this summer.

The £5m midfielder, who pulled out of Tuesday's Under-21s 1-0 defeat to Norwich, said yesterday he's never asked to be paid up the two remaining years on his contract.

"I'm sure something will open up for him as we go along," said Jackett.

"He didn't play on Tuesday - there was a last-minute problem of a personal nature, nothing major.

"Jamie is available for transfer or loan and it will be exactly the same in the summer when the window opens again."
