Nwankwo Kanu's declaration that he intends to leave West Bromwich Albion if they are relegated from the Premiership will have surprised nobody - least of all manager Bryan Robson.

The Nigerian striker, who earns around £25,000 a week, has only started nine games since Robson took over last November and the 28-year-old forward has become something of an expensive luxury at The Hawthorns, where he is below Kevin Campbell, Geoff Horsfield and Robert Earnshaw in the attacking hierarchy.

Consequently Kanu is widely expected to leave in the summer regardless of what division Robson's team are in. Midfielder Jason Koumas could also be heading for the exit.

However, Robson says players who are integral to his team, such as Zoltan Gera, will not be sold unless Albion receive an irresistible offer.

"Zoltan works hard for the team, is a lovely lad around the place and a good professional," said Robson, responding to speculation linking Dutch side PSV Eindhoven with a move for the 25-year-old Hungarian.

"There is absolutely no chance of Zoltan going anywhere unless someone wants to pay me, like, £20 million - which I think would be good business for the club!"

Robson was less complimentary, though, about Koumas - who has started just three matches since he took over.

Like his predecessor Gary Megson, Robson has bemoaned Koumas' apparent reluctance to heed advice to work harder defensively in matches.

It appears increasingly likely that the Welsh international, who signed a four-year deal last July, could leave when Robson trims his 26-man squad at chairman Jeremy Peace's request.

Robson said: "What Jason has to take on board is this: Are myself and Gary Megson both wrong?

"Jason has great ability but I told him he has a few weaknesses in his game which he has to improve on and, for me, he has still got to work on those.

"Until Jason grasps that, then he will struggle to get in any Premiership side - it's up to him."

Robson will decide Koumas' future in the summer, but Kanu plans to activate a get-out clause in his contract if Albion, who are 19th, are relegated.

"If the team goes down, I will leave," he said. "I don't want to be playing in the lower division, as it is not good for my career."

Albion have sold out their allocation of 2,800 tickets for next month's trip to Middlesbrough.
