Chelsea manager Jose Mourinho spoke publicly for the first time in 10 days today and refused to hide his simmering resentment towards the media over Diego Costa's three-match suspension.

The Blues boss, who risked a Premier League fine for avoiding media duties either side of last weekend's draw with Manchester City, was unhappy with the portrayal of a challenge between Costa and Liverpool's Emre Can, which resulted in the Chelsea striker's ban.

Asked why he had not spoken to the media since immediately after advancing to the Capital One Cup final at Liverpool's expense on January 27, Mourinho said: "Because if you (the media) want, you can make a silence very noisy. Depends what you want to do.

"You could make noise with my silence, because you know the reason for my silence. It depends on you. If I was a journalist I could make from silence, lots of words."

Mourinho in December spoke of a "clear campaign" against his side.

He was fined £25,000 the day after the Liverpool win for those comments.

Asked if the reason for his absence was because of Costa's suspension, which continues at Aston Villa on Saturday, Mourinho, who chose not to discuss the incident, said: "Not just (Costa's ban). I don't reflect. Maybe I'm punished to reflect.

"Maybe they (football's authorities) can read my reflection and (that) I don't want."

Managers are required to speak before and after matches under Premier League broadcast regulations.

Mourinho, who often wears a smile but did not on Friday, added: "You know why I'm here so you cannot expect that I'm super happy to be here."

Mourinho responded "yes" when asked if he was in attendance because he was required to be.

He risks a fine from the Premier League for his absence, although possibly not as big a financial penalty as the one which he would likely have been subjected to had he spoken around the City clash.

"You know the only surprise I had in relation to that was to be punished when I was pushed by another manager (Arsenal's Arsene Wenger)," Mourinho said.

"Apart from that I can expect everything."
