Chelsea are growing increasingly frustrated with John Terry's refusal to commit himself to the club.

The Stamford Bridge captain is being tracked by cash rich Manchester City, and has already been the subject of a £30million offer - a bid that was quickly turned down by the Chelsea hierarchy.

Throughout the ongoing saga, Terry, who could earn £300,000-a-week if he chose to join Mark Hughes' Eastlands revolution, has been reluctant to slam the transfer talk, a stance that, according to the News of the World, has infuriated Blues owner Roman Abramovich.

Chelsea are now bracing themselves for an improved bid from City, and have told Terry to put on a public show of loyalty or hand in a written transfer request.

The move has been instigated by new Blues boss Carlo Ancelotti and backed by Abramovich.

Sources within Chelsea fear that Terry, who already earns an amazing £140,000-a-week, may use the situation to demand Chelsea increase his earnings, something the club may be willing to do. They will not, however, match City's financial package.

The latest news surrounding Terry, comes in the same week that the England international urged his Chelsea teammates to give their total support to Ancelotti.

"Next season we need to make sure we start a lot better than we did last year and really push for the Premier League because I would love to win that trophy again, as well as being back in the mix for the Champions League," said Terry.

"It is important we realise Ancelotti is going to be here for a good few years, he is going to bring in his own players, staff and training methods.

"We need to adapt to that and move Chelsea in the right direction."
