I went through terrible moments opening the batting and captaining the side. I could not buy a run in my first series against South Africa and really struggled in Sri Lanka. It was killing me going to my room at night hating this job. I used to ask: “What am I going to say in the morning?’”You have to keep smiling and acting. Being able to act is an important part of being a captain. But sadly the more you act the more you are giving out a false message. I am sure Cook has been fine in the dressing room because he has been acting but in his own mind he cannot have felt in a great state over the last few months. Too much has happened.
