"If I don't do well, I have to consider my future. At the moment we are not there.
"I have to consider that at my age, you always have to assess if you have the fitness, the desire, the commitment that this job demands.
"Then of course you have to make your decisions. I hope I will be lucid enough and intelligent enough to assess my performance well.
"Two years is a long time in my job. I just want to do well for the club as long as I can and accept all the rest."

The 29-year-old right-back was quoted in French newspaper L'Equipe questioning the club's transfer policy, which has seen midfielder Alexander Song leave this summer along with striker Robin van Persie following the exits of Cesc Fabregas, Samir Nasri and Gael Clichy last year.
