Charles N'Zogbia 'unhappy' at Aston Villa

Aston Villa winger Charles N'Zogbia has raised concerns over his future at the Midlands club after claiming that he is 'unhappy'.

The 25-year-old appeared angry at boss Alex McLeish's decision to substitute him for Emile Heskey during Villa's 2-1 defeat to Newcastle United yesterday.

The winger turned to Twitter and said: "For the first time in my life I'm not happy playing football."

N'Zogbia, who moved to the Midlands club last summer, later deleted the tweet from the social network site.
