Manchester United defender Rio Ferdinand doesn't believe Chelsea's recent problems can be blamed on the absence of key players.
Ferdinand is not convinced the recent absence of Frank Lampard can entirely account for Chelsea's misfortune, even if he rates his old West Ham team-mate as their best player.
"Frank has been a big loss for them," said Ferdinand.
"I would say Frank is their best player. He gets 20 goals a season from midfield, which is huge.
"Any team that loses that is bound to be affected.
"But Chelsea would say themselves they are not a one-man team.
"Frank missed a few games earlier in the season but no-one was saying anything then because they were winning games.
"When a club loses games people look for excuses. Frank being out is one that has been brought up a lot."
