N’Zogbia signed for Alex McLeish’s side in the summer for a fee believed to be around £9.5 million, but he has struggled to maintain the level of performance that made him a wanted man at the DW Stadium.The Frenchman scored the equaliser in Villa’s recent 2-2 draw with QPR and picked up an assist at Newcastle in their last fixture but, after getting substituted a little later, he has declared he is feeling the lowest he ever has in football.Taking on Twitter, he said: “For the first time in my life I\'m not happy playing football.”McLeish is yet to comment on the post, which has since been deleted from the site, but it is clear all is not well at Villa Park with the side lingering down in 13th place after just two wins from their last 11 league matches.Taking into account the team’s recent form, things aren’t going to get any easier immediately, with Manchester City their next opponents as Roberto Mancini’s side visit Villa Park on Sunday.
