AC Milan defender Alessandro Nesta rates Chelsea a bigger Champions League threat than Manchester United.

The Rossoneri went through in second place behind Real Madrid and as such could have a very tough opponent in the second round.

"Barcelona and Chelsea are the toughest and I really would not want to meet them yet," confessed defender Nesta during a charity visit to a local children's hospital.

"We can happily challenge all the others, even if Manchester United also remain very strong."
