Man Utd's Carrick 'shocked' at sending off
However, following a first red card of his professional career, Carrick feels he was harshly treated by the decision, which rules the England international out of the second leg of the UEFA Champions League last-16 tie in three weeks' time.
"It was very soft to be honest," Carrick told Sky Sports News.
"It rolled at me and I flicked it into Pat's path as he's ran past me.
"It wasn't as if there was a player from their team trying to get it and it didn't slow the game down in any way.
"I was just shocked really, to be honest."
Asked if he spoke to the referee about the incident, Carrick replied: "What can you say really?
"He said it was for kicking the ball away, but I don't believe I kicked the ball away to be honest.
"I didn't slow the game down in any way, I was just surprised more than anything."
