The West Ham United striker, on loan from Liverpool, had words with Manchester United's Rooney and also clashed in the air with United keeper de Gea whilst also trading elbows with Nemanja Vidic but said none of it was untoward.
"It was great, a tough battle, I enjoyed every minute and getting stuck in, getting a few elbows and giving a few. It's all part of the game," he told Sky Sports 2.
"It was a bit of friendly banter with me and Wazza (Rooney).
On the de Gea incident for which he was booked, he added: "I went for the ball. I was running straight in and couldn't stop at that moment."
And regarding his potential stay in East London, Carroll was open to that possibility: "I've loved every minute and the lads have been excellent.
"We will have to wait and see what happens."
