Claude Makelele admits some Chelsea players will be happy that Jose Mourinho has left.
"Nobody thought we would not beat Rosenborg on our own pitch but we can make amends by beating Valencia - even though it will not be easy.
"This game is a lot more important for Chelsea than it appears to people. We are playing for our future in the Champions League because to get only one point from six would put a lot of pressure on us.
"Valencia want to pay us back for last year and that will make the game even harder, but Chelsea have lived through worse situations and we have come through."
