I'm not happy at United: Berbatov

The 31-year-old was linked with a move away from the Red Devils in the January transfer window but no deal was completed and it is now expected that the club will activate a one-year extension to his contract � a clause written into his deal when he signed for United from Tottenham in 2008.
Berbatov has started just five of United's 24 Premier League matches this season and was famously left out of the matchday squad for last season's Champions League final.
He told Bulgarian sports website www.sportal.bg: "I am a Manchester United player, but I do not currently play in as many games as I want. I'm not happy that I do not play. But I cannot blame anyone.
When I have something to say, I go and talk face to face with the manager. He decides everything."
Speaking about his future at United, Berbatov added: "There was nothing concrete as an offer to me. I read about such things, but they are more speculation. I do not know how long I will stay at United.
