Karl Robinson reckons MK Dons went from strength to strength after he took his frustration out on Jon Otsemobor in their 2-0 win over Carlisle.
Luke Chadwick's first-half curler and Ryan Lowe's first goal for the club handed the Dons their first win in three league games.
But Robinson felt his side were in danger of throwing the game away until he lashed the ball at new full-back Otsemobor early in the second half.
"I thought Carlisle were excellent for the first 20 minutes of the second half and really put us up against the wall," said Robinson. "But once we got to grips with it and people had a go at each other we went from strength to strength.
"I said sorry to Semie (Otsemobor) because I've kicked the ball at him a little bit fiercely just out of frustration. I've just apologised to him but it wasn't meant at him. There was a sloppy pass and I shouted and gave it back to Semie, but he just stared at me with that big chest of his!
"I just felt that because we felt a little bit comfortable in the first half we just didn't think we had to turn up, but Carlisle are a good side and if you don't turn up against them you're going to find yourself on the wrong side of a result. But overall I felt our play probably deserved more than we got. We looked very comfortable and it was very pleasing for me."
