Inter Milan coach Jose Mourinho said on Tuesday he was not certain to stay at the Champions League finalists next season as his team prepared for the first part of its assault on an unprecedented Italian treble.

Inter meet Serie A title rivals AS Roma in the Italian Cup final on Wednesday but with the outspoken Mourinho giving a rare domestic news conference, questions about his future flowed.

Asked if he would stay next term, he said: "I can't say it, in football you can never say a thing like that."

The Portuguese has a contract with Inter until 2012 but has consistently said he does not like Italian football, fuelling media speculation he could soon end up at Real Madrid or return to his beloved English Premier League.

Mourinho, who won the scudetto with Inter in his first season in charge last term, became so fed up with grillings from the Italian media and soccer authorities that he stopped doing non-Champions League news conferences two months ago.

The former Chelsea coach decided to waltz back to the stage on Tuesday, given that the Cup final was a special occasion, with his acid tongue in tow.

His main target was Roma president Rosella Sensi, who said Inter should be ashamed of their 2-0 victory at Lazio on Sunday where home fans cheered the goals because they want the league leaders to beat bitter rivals Roma to the title.

"The lady may be president, a doctor, she may be born in a golden crib but she must give us respect," Mourinho said, before criticizing the long-made decision to hold the Cup final in Roma's Stadio Olimpico home.

"They are lucky to play the Italian Cup final at home, a unique thing in the world because I don't know any other national cups which finish at the home of one of the finalists."

Inter, meeting Roma in the final for the fifth time in six years with two wins each, will be without injured centerback Lucio while influential playmaker Wesley Sneijder is doubtful.

Roma coach Claudio Ranieri, whose side can still win its first double if it beats Inter in the Cup and overhauls the Milan side's two-point lead with two games to go in Serie A, was in a charitable mood by contrast.

The 58-year-old declined to discuss the Lazio controversy and played down his rivalry with Mourinho, who followed him as Chelsea coach and once labelled the Roman "a 70-year-old".

"My relationship with Mourinho is good, I admire him both as a coach and person, he's doing extremely well in Italian football as well, so really he deserves everything he's getting," Ranieri said.

He reckoned the match was "50/50" but acknowledged the fact the game was being played in Roma's Stadio Olimpico home could boost his players.
