McClean was hammered during the week by Republic of Ireland coaching staff and teammates after blasting Giovanni Trapattoni last Friday.
"It was idiotic and a bit frustrating from me but now I want to put the matter behind me," said McClean after his 30-minute runout against Oman. "At the end of the day, I am human like anybody else and showed my frustration. I have learned from it. I have stopped tweeting, Facebook and all them social networking sites."
