The Portuguese is on course to lead Inter to a fourth consecutive Serie A title in his first season at the club, with his side 10 points ahead of Juventus and AC Milan with six games to go.
The winner of two Premier League titles during a three-year stint at Chelsea, Mourinho has previously said he would like to return to coach in England one day.
"England is a paradise for the coaches who can plan for the future without the pressure of winning in the short term," he told the club's Web site. "(Arsene) Wenger works in tranquillity. Arsenal hasn't won a title in four years but he continues his fantastic work with young players. I think (Liverpool boss Rafa) Benitez will miss out on winning the Premier League for the fifth time but he continues his fantastic work and his contract gets extended."
"In Italy I think 10 coaches have already been replaced this season. Here there's the obsession with results. Italian coaches are good technically but they are also good at handling this type of pressure."
The comments are to fuel speculation Mourinho will not stay at Inter beyond the end of his contract in 2011.
"My contract is for three seasons," he said when asked if he would remain longer than his predecessor Roberto Mancini.
