On-loan goalkeeper Thibaut Courtois has been warned to watch out for Jose Mourinho’s mind games as Atletico Madrid and Chelsea prepare to lock horns in the Champions League. Courtois will play against the club who own him in the semi-final on Tuesday night with ex-Stamford Bridge midfielder Tiago backing him to cope with the pressure. ‘We all know Mourinho and we all know that if it is necessary to crank up the pressure before a game in order to win it then he will do that,’ said Tiago. ‘Jose just wants to win. He knows that Courtois is very important for us and he protects his own interests as any coach would. He wants to weaken us as any opposing manager would.’
