Pep Guardiola said he took Kevin De Bruyne off during Manchester City's win against Bayern Munich in the Champions League quarter-final first leg because he wanted more energy in the side.
De Bruyne had just had treatment for a knock on his leg before being replaced and he reacted badly to the decision. He ignored Guardiola as came off for Julian Alvarez and then waved a dismissive hand after walking past the City manager.
Guardiola said the decision was entirely tactical and dismissed De Bruyne's reaction, saying making those decisions was his biggest strength as a manager.
