This season's Inter, who now head to the Champions League final seeking an unprecedented treble for an Italian club, are radically different to the side which Mourinho guided to the scudetto in his first season in charge last term.

Then they often relied on long balls to striker Zlatan Ibrahimovic but since his departure to Barcelona last July, Inter have become more of a passing team but with the same immense physical strength and rock-hard defence.
Mourinho has been his usual controversial self, locked in a battle with the Italian media and football establishment who have struggled to come to terms with his outspoken character.
Amazingly for someone so talkative, he even stopped doing domestic news conferences for three months because he was so frustrated with the criticism of his emotive behaviour.
But in the sanctuary of Inter's training ground Mourinho has a very different relationship with his players and portrays himself as a worker bee, buzzing about for the good of the team.

A sudden rush of draws in February slashed their nine-point lead and a bruising defeat against title rivals AS Roma in March meant the path to the scudetto was out of Inter's hands.
Mourinho did not panic and his players rewarded him with superb displays in reaching the Champions League final, winning the Italian Cup and seizing control of Serie A again.
"We have full confidence in ourselves and now we have this great manager and he can transform the team in any way," midfielder Sulley Muntari told Reuters.
