West Ham United boss Gianfranco Zola admits he wants to buy a new striker.

Zola, however, refused to elaborate on any of their alleged targets.

"I won't talk very much on that because it's work in progress," said Zola. "The club is dealing with that. We had a chat and we think everything is clear.

"Now we need to keep working on that. I really can't say too much because we're straight into the middle of a battle.

"We've been linked with too many strikers. There are so many. It's pointless for me talking about it. We're talking about good players, certainly.

"For me, though, it's only talk. I don't want to get too involved in that. My focus has to be on tomorrow's game against Portsmouth. Many, many, many names. But I rely on the club. They're working to make this team stronger.

"I don't know where Ruud van Nistelrooy came from really. We knew we were looking for strikers and I knew it would be difficult. I didn't put too much faith in that move. That's it, really."
