Tough fast bowling is not nice. You have sleepless nights. I had them over facing Waqar Younis, Brett Lee and Shoaib Akhtar. You worry you will be embarrassed or could get hurt. But you have to accept it. If it goes wrong you get dropped, go away and become a stronger player.
Joe Root lost form in Australia. He tried to fight through it but was dropped. Matt Prior lost his place after three Tests. I am sure he would openly admit he went back to his room and broke down on a couple of occasions. But he accepted his fate, said he would come back fitter and stronger but more importantly stayed on tour.
What Trott will have to accept is that players in his own dressing room and in the opposition will look at him and think at the toughest of times he did a runner. He did not fight and got on a plane and went home. It is harsh but that is the reality.
