Manchester City 7 Norwich City 0: Chris Hughton's job under threat after thrashing at Etihad Knocked out of the Capital One Cup at Manchester United 4-0 on Tuesday, Norwich produced an even more desultory performance across the city, leaking four goals in the space of 21 first-half minutes as their hosts recorded their largest top flight league victory since 1968. With supporters already applying pressure on their manager, the latest defeat, which now means Norwich have taken 27 points from their last 31 games, will hardly strengthen his position in the eyes of chief executive David McNally. "I've always had a confidence in my ability and with the group of players who are in that changing room," said Hughton. But we need to change and address this one very, very quickly. It's early in the season but we are on the back of a heavy defeat today. We all let the club down today because I'm the manager and I pick the team, I determine the tactics of the team. Our support travelled up to Manchester in midweek, we had almost 3,000 there, and they had to come back for today's game. We have certainly let them down. The emphatic victory, not to mention their first clean sheet in the league since mid-September, vindicated Manuel Pellegrini's controversial decision to drop England goalkeeper Joe Hart, replacing him with little-used back-up Costel Pantilimon. "I don't know when," said Pellegrini when asked when Hart could expect to return to the starting line-up. I only know he must work very hard. He knows he must do it and he will have all the support of me and the goalkeeping coach because I think he's a top player. He's number one for England and I'm sure he will return to the normal performance he has had for two and a half years now.
