Chelsea chairman Bruce Buck has urged fans not to protest during games over ticket prices.

Chelsea fans have been threatening a boycott of the next Champions League game against Genk on October 19 because of ticket prices but Buck urges caution.

"We're comfortable that [Stamford Bridge] is going to be full. The manager, Andre Villas-Boas, looks on it as a big match and will want the fans to come and support the club.

"JT [John Terry] and all the other players recognise it's an important match and are asking fans to support them.

"I understand supporters saying they would prefer lower prices but we try to spread the balance; I think we've got it about right, but I do understand that some people would disagree."
