Jose Mourinho claims he is a “victim” of his past success as he took a swipe at Manchester United.
The Special One was unveiled as Roma boss having swiftly found work after leaving Tottenham.
It was his third sacking since 2015 following dismissals at Chelsea and Manchester United.
For years Mourinho was regarded as one of the best managers on the planet, but he has found success harder to come by in recent seasons.
Despite that he has continued to win trophies, picking up three in one season at United. Those successes remain the last time the Red Devils won silverware – a fact Mourinho was keen to underline.
“I’m a victim for what I’ve done in the past,” said Mourinho.
“For others, my ‘disasters’ are a success. I won 3 titles at United and they were not even considered and they stole me a cup final at Tottenham”.
Solskjaer has guided United to just the one final in his two seasons in charge, losing to Villarreal on penalties.
Mourinho has now returned to Italy for the first time since leaving Inter Milan in 2010.
Roma’s last Serie A title came in 2001 but the Portuguese coach is determined to end that wait.
Henrikh Mkhitaryan and Chris Smalling both worked under Mourinho at Old Trafford and he has reiterated the need for players to embrace his principles.
He said: “We must never forget our past, but we must build the future, a sustainable situation over the years but with great passion. Now it’s time to work, even with my men
“The first steps to change mentality? I need to know the group. There are non-negotiable principles, the way to work is simple. It is something that concerns all of us at the club, not just the players”.
“The next is always the most important challenge of my career. So now it’s Roma. If Serie A is not seen abroad as a big league, it is our fault and we need to do something more”.
Mourinho was also quick to poke Roma’s rivals as he took aim at champions and former employers Inter.
The Nerazzurri won Serie A for the first time in over a decade, but have since waved goodbye to Antonio Conte as they deal with financial difficulties.
Star players could yet follow him out the San Siro exit door and Mourinho referenced their money problems.
He said: “The owners don’t want isolated success. It’s even more difficult when you push for sustained success because it’s easier to win in isolation.
“It’s even easier if you win and you don’t pay the players their wages.”
