City surged into a two goal lead against Fulham on Sunday after goals from Joleon Lescott and Martin Petrov from but had to settle for a draw when Damien Duff and Clint Dempsey pulled it back for the Whites.

Hughes' men began the campaign with four clean sheets, but have now kept just one in their last seven matches.

Despite bringing in Joleon Lescott, Kolo Toure, Wayne Bridge and keeper Shay Given to shore up the defence, Hughes admits more work is needed on the training ground.

"We knew the threat Clint Dempsey posed at set- pieces and haven't dealt with it," said Hughes.

"We've been caught out a couple of times and that's been prevalent this year.

"We started this season well with our defending but our goals against column is still not bad.

"I don't think it's just us, it's happening a lot. Often it's to do with delivery rather than poor defensive play.

"But there are always areas that we can focus on in training, that's what we'll do. The important thing is we learn from our mistakes."

The point gained along with Liverpool's win over Manchester United leaves City sixth in the Barclays Premier League table.
