Bolton Wanderers boss Owen Coyle knows Adam Bogdan is unhappy being dropped for Jussi Jaaskelainen for their draw with Manchester United.
Coyle claims he is happy to get a few angry knocks on his office door, if it means having a more competitive squad.
"Adam had been playing out of his skin and it was disappointing for him - in fact I told him to be disappointed, because of how well he had done," he said.
"It was a big decision but as a manager, that's what you are charged with, so we'll do it again."
