The Observer says Mourinho holds Terry responsible for charges levelled by Chelsea's board of directors that he had lost the support of his playing staff after Tuesday's Champions League draw with Rosenborg - a match that was followed by club owner Roman Abramovich lecturing a senior professional on his on-field tactics behind Mourinho's back.
Midway through the first half Rosenborg scored, after Miika Koppinen beat Terry at a set piece. When Mourinho then directly criticised the centre back's defending at half time, Terry refused to accept responsibility for the goal or even to respond to his manager.
Chelsea chief executive Peter Kenyon was made aware of the dispute and, according to the dressing-room source, presented the information to an emergency board meeting on Wednesday as evidence that the manager had lost the trust of key players. The club subsequently asked Mourinho for his resignation, which he refused to tender, but ultimately settled on dismissal by 'mutual consent'. Later on Wednesday, Mourinho sent Terry a text message sarcastically thanking him for talking to the club's hierarchy.
