France international Florent Malouda has not ruled out the possibility of a move away from Chelsea at the end of this season.
The 29-year-old has become disillusioned with a lack of first-team opportunities this term under Carlo Ancelotti and is willing to move elsewhere in order to further his career.
He told L'Equipe:"Carlo Ancelotti's tactical system is physically very demanding. Recently we showed less intensity, the game was less fluid. But that system allowed us to be in our current position. All the players support it.
"Before the match against Birmingham City, I talked to the coach. I told him about my frustration. I believe I have succeeded in my start to the season, but during the key matches against Arsenal or Manchester United, I was on the bench.
"I have ambitions for the World Cup, and considering my status in the French team it is a little annoying (being on the bench).
"Ancelotti is aware of it. But currently I am paying for that system. It is not that easy for him either, he has a big group to manage.
"The frustration is big matches. However, if there is no place for me in that system, I could go somewhere else.
"Finding a new club is not a problem. But the club has closed the door to any departure either in January or in June. The coach relies on me.
"I feel fine at Chelsea. But now, things have to change. When I came I was labelled as Mourinho's player. I have known five coaches and each time I have had to start again from scratch. Last season I earned a key-player status. Today it has been questioned again."
