Chelsea manager Jose Mourinho is heading for another confrontation with the Football Association after piling pressure on them to take action against Reading's Irish midfielder Stephen Hunt for the challenge that caused Petr Cech to require neurosurgery.

The FA, who have not received any paperwork from Chelsea on the matter, are privately not inclined to pursue Hunt and have taken the view that determining intent on Saturday's challenge would be difficult in the extreme.

But Mourinho last night accused Hunt of being "an amateur" with "no sense of responsibility", adding: "The FA is there to do something and I will be curious waiting for the decision.

"For me it was a very, very bad situation. Maybe the boy is only professional for a year, maybe was an amateur and has no sense of responsibility. I don't know. Maybe he didn't sleep before the game and was too excited about playing against Chelsea. I don't know what happened but it was very, very bad."

A statement by the club on Sunday indicated Chelsea would be writing to the FA with their observations; it is understood the letter has not yet been drafted. It was initially believed that having reviewed the fall-out from Saturday's fixture the club no longer wished to adopt an aggressive stance, but Mourinho's vehemence suggests otherwise.

Referee Mike Riley did not mention the incident in his report.

There will also be no action taken against Reading defender Ibrahima Sonko, who Mourinho felt should have collected a second booking after he collided with Cech's replacement, Carlo Cudicini, in injury-time, leaving the Italian unconscious.

Cech is likely to receive a letter from Hunt this morning after the 25-year-old made a statement yesterday, expressing his concern for Cech and maintaining the incident was "a complete accident".

"I can guarantee that I did not attempt to injure Petr," said Hunt. "I am very upset that the collision has resulted in such a bad injury. When Petr slid in to collect the ball, our momentum meant that a collision was unavoidable. I think the TV pictures show that the collision was a complete accident, and I'd like to think that my team-mates and opponents throughout my career in football would say that I'm not the kind of person to deliberately hurt an opponent.

"Serious injury is the worst part of football and I feel terribly sorry for Petr. I have written to him to wish him a full recovery."
