"Mikel came in with his studs up and that was in the back of my mind. Then I thought there was another foul in there and obviously I've lost my head," said the striker.
"There are no excuses for the tackle I made but if the referee had pulled the foul up when he should have done it wouldn't have happened.
"A lot was going their way and I think frustration got the better of me. You give and take with referees and sometimes the decisions go for you and sometimes they don't so you can't always blame them."
