Chelsea head coach Antonio Conte has no regrets over his escalating feud with Jose Mourinho.

Conte has become embroiled in a war of words with his Manchester United counterpart over the past week after Mourinho made reference to unnamed coaches behaving like "clowns on the touchline".

This was widely interpreted as a swipe at the ever-animated Conte, who responded by accusing Mourinho of having "demenza senile" in his native Italian – Chelsea later maintained their boss was searching for the word for amnesia – and forgetting his actions in the past.

The Portuguese then took the invitation to delve into Conte's past and reference the ex-Juventus and Italy coach's four-month ban for allegedly failing to report match-fixing at his former club Siena.

The 48-year-old was subsequently cleared of any wrongdoing and branded Mourinho a "little man" after Chelsea's 0-0 FA Cup draw against Norwich City on Saturday.

Chelsea are back in action against Arsenal in the first leg of their EFL Cup semi-final at Stamford Bridge on Wednesday and, with the unseemly spat still prominent in the pre-match discussion, Conte insisted he had no cause to question his own conduct.

"I have this look – a person that regrets? I don't think so," he said.

"I think we both said the things and we'll see what happens in future."
