Mourinho was happy living in London until dog day afternoon

Mourinho claims the clashes he had with Chelsea's billionaire owner Roman Abramovich and Arsenal manager Arsene Wenger were nothing compared to his run-in with police officers over Yorkshire terrier Leya.

Police raided Mourinho’s Belgravia home 13 months ago over claims the animal had been taken in and out of the country breaking quarantine rules.

Mourinho's pet eventually returned to Portugal with his wife Tami.

Mourinho told The Sun: “My family was very happy in London.

“It was a fantastic city for us, a great experience and especially on a social level.

“The only problem I had in London was the incident with my dog — but I don’t think it’s a problem in Italy.”

Mourinho, who will have Leya with him at the San Siro, has promised his new club his undivided attention and unrelenting hard work.

He said: “I work with passion, I work well, my rapport with the players is very strong, it’s always been strong and will be strong again this time.

“I think the sporting results arrive with tranquillity and it’s the natural consequence of good work.

“My self confidence is always strong and I always say that my players are the best in the world.”
