Di Matteo tells players on yellow cards not to change game
Petr Cech believes it is important that an experienced referee will be in charge of Chelsea's clash with Barcelona, while Roberto Di Matteo has told those players one yellow card away from a suspension not to change their games.
Cuneyt Cakir will be the man in the middle at Camp Nou on Tuesday and Blues goalkeeper Cech has backed the Turkish official to put in a strong performance in what will be his first knockout-stage match in the competition.
Chelsea-Barca ties have been dogged by refereeing controversy since the sides first met in the competition seven years ago.
Cech, who has featured in most of the Blues' nine matches with Barcelona since 2005, said: "The referee can be a big part of the game. You could see that in the past.
Professional
"There were great games between us and Barcelona but there was controversy, which was a shame, overshadowing the great games on the pitch.
"We have an experienced Turkish referee.
"If you have an experience of refereeing Galatasaray and Fenerbahce in the Turkish league, a game between Chelsea and Barcelona should be fine.
"The referee will have the same professional approach as we had in the first game, which was without controversy."
Meanwhile, five Chelsea players are a booking from a ban which would rule them out of the final but Di Matteo said: "We will just have to play without thinking about it.
"They know who is at risk. A lot of them have played here before, so it's not a new environment."
Branislav Ivanovic, David Luiz, Ashley Cole, Ramires and Raul Meireles are the players who will be treading a disciplinary tightrope as Chelsea aim to protect a 1-0 advantage from the first leg.
