The former French international insists his East London switch was the worst move of his career.
Alou Diarra is currently playing his football with Championship side Charlton Athletic, but his 16-year career is one littered with many trials and tribulations throughout a number of different countries.
The 34-year-old has been on the books of Bayern Munich, Lyon, Liverpool, Bordeaux, and Marseille, just toname a few, but there is one move that he has admitted irks him more than any other.
The former French international went on to make just a handful of appearances for the Hammers over a two-year spell, and was most noted for declaring amid his time there that signing for the club was a 'waste of time'.
As reported by the Guardian in 2013, Diarra quickly become disillusioned by the treatment he felt he was getting at the club, and again on French TV, made his feelings known about the Premier League switch, declaring: "I have wasted my time."
Since leaving the Hammers in the summer of 2014, the veteran midfielder has wound up in the Championship with Guy Luzon's Charlton side, as his career inevitably slows to a halt.
The Addicks currently sit in 15th place in England's second tier, after winning just two of their opening eight fixtures. However, on Diarra's part, the Frenchman has been noted on a number of occasions already for some strong performances playing at the heart of the team's defence.
