Mourinho’s squad was comprehensively exposed in Saturday’s FA Cup fourth-round tie against League One Bradford City, who came from 2-0 down to win 4-2 at Stamford Bridge.
Mourinho had made nine changes from Tuesday’s Capital One Cup semi-final first leg match against Liverpool and he said afterwards: “I don’t want to speak too much about this, but it is easy for you to understand now why I play almost every game with the same players. I don’t make many changes. I try to keep stability in the team. Maybe now you can understand a bit better why.”
