Ivan Campo and Gary Megson have warned Atletico Madrid of a battle when the visit Bolton Wanderers tonight for their UEFA Cup clash.

Campo, who won two Champions League titles at Real Madrid, is in his sixth season in the Premier League.

Incredibly, he was not registered when the competition kicked off last autumn but he is certain to start this evening.

He said: "In essence, Bolton are an old-fashioned English team. We work as hard as we can, and we will try to make Atletico suffer. Even if they do well in Bolton, we won't give up in Madrid. We fight all the way. Atletico won't find an inferno when they turn up at the Reebok. It isn't that intimidating. But if we start well and score, then they will see an atmosphere."

Bolton manager Megson confirmed that his team's approach would be uncompromising.

"What Ivan is saying is that we have qualities that you don't always find in Europe," he said. "They expect more time on the ball, they are used to that. He's a better judge because he has played in both.

"They won't get kicked around. But they will be challenged. Set-pieces will go into their box. They will have to be brave physically, they will have to put their head in there. They will have to play at a Premier League tempo.

"We have to play a style that helps us, that we are used to and that they can't cope with. We have to find as many ways as we can of winning that game. If the full back can't head it, that's where it's going. If they don't like it behind them, then we will do that."
