A decade has passed since Inter Milan beat FC Barcelona in one of the UEFA Champions League's greatest-ever matches, and Jose Mourinho has finally revealed what he whispered in Pep Guardiola's ear before his side's remarkable triumph.
In the 2009/10 UCL semi-final between Inter and Barca, the Nerazzurri recorded a 3-2 aggregate victory over their Spanish opponents, with the second leg becoming famous for Mourinho's mysterious whisperings in Guardiola's ear.
Having won the first leg 3-1 at the San Siro, Inter went 1-0 down (3-2 up on aggregate) in the return fixture and looked destined to surrender their lead when Thiago Motta was sent off for a foul on Sergio Busquets.
The former Italy international's dismissal sparked premature celebrations by the Barca players, who believed they would go on to win the match, but Mourinho has now revealed that he knew the tie was not over.
"When Busquets fell stunned to the ground, I was between my bench, Barcelona's bench and the place where Thiago Motta was expelled," Mourinho told Gazzetta dello Sport.
"Out of the corner of my eye, I saw the Barcelona bench celebrating it as if they had won, Guardiola calling [Zlatan] Ibrahimovic to talk about 11 against 10 tactics.
"I simply said to him [Guardiola], 'Don't party now because this isn't over yet.' This defeat was the most delicious of my career. On the field we have to find solutions and we didn't lose 0-1, we won 3-2 in epic conditions!"
Inter made the most of their triumph by beating Bundesliga giants Bayern Munich in the final of the competition, with Mourinho later being named FIFA World Coach of the Year for his exploits.
