Tony Cascarino hails Chelsea for agreeing deal for Ajax forward Hakim Ziyech – 'He's got EVERYTHING'
Speaking to the Mail in 2018, Terry revealed how Mourinho got inside his head off the back of a title-winning season.
The ex-England skipper said: ‘He embarrassed me after one pre-season, after we had won a league title.
“He stopped the training session, came in, threw down his pad. ‘If you keep giving the ball away, I will go and buy someone for £50million’.
“I am thinking, ‘I played every game for you last season! And now you’re trying to humiliate me!’
“I didn’t understand why he was doing that, but my instinct was to run and give everything; flying into tackles, winning the ball.
“We made eye contact and he grinned. He knew exactly what he was doing – to get the best out of all of us.
