Bolton boss Gary Megson admits his side needs to be better when they take on quality opposition.

The Trotters were swept aside 4-0 by a destructive Chelsea in the fourth round of the Carling Cup and Megson knows his players need to improve when they meet quality players.

"We didn't play as you need to play against the quality they have," said Megson.

"If you don't play at a tempo that might upset Chelsea, or go into challenges that might upset them, then you're not going to damage them.

"It was a poor performance from minute one. We needed to score the first goal, but we were never going to do that with the way we approached it."

However, Megson did say that his club was not able to compete with the likes of Chelsea in regards to the purchase of players and it showed when the Blues were able to bring on big-name substitutes in the second half.

"When you can put a £28million sub on - that's as much as we've spent in two years," he added.

"We can't compete with that on equal terms. Chelsea are stronger than other teams in terms of physical strength, they're quicker, and all the teams that are in the quarter-finals are probably in the top eight of the Premier League.

"I'm pleased to be playing them again on Saturday. We need to put on a performance. That was a bit of a stroll. Our team will be different, not just in personnel but in approach, and I hope we're a lot more wholehearted than it was tonight."
