Sneijder has spoken of how Tottenham manager Mourinho dealt with a teenage and rebellious Mario Balotelli within his Inter squad of pure professionals.
"Mourinho protected us always – but you don't mess him about," said Sneijder.
"Mario Balotelli tried it. He was young and thought he knew it all. And when Mourinho was not using him a lot, Mario walked in my hotel room one night when I was with a few other players.
"It was 10.30pm and he said, 'I am leaving the camp, the manager is not taking me seriously. I want more playing time'.
"Mourinho later told us Mario was only welcome back again if he apologised to the entire squad and to him, the manager.
"Mario did exactly that and they came back with their arms around each other's shoulders. It was all good again – at least that's what Balotelli thought.
"During the Champions League final, Mourinho told Balotelli to do a warm-up for 45 minutes, then let Marco Materazzi warm up for five minutes. Materazzi came on, Balotelli didn't. Mourinho has his own laws."
