Republic of Ireland winger James McClean has admitted that his rant on Twitter against coach Giovanni Trapattoni on Friday was "stupid".
The 23-year-old complained about being an unused substitute in his side's 2-1 away win against Kazakhstan in their opening game of the 2014 World Cup qualifying campaign on the online social networking website.
McClean was reprimanded by Trapattoni in front of the entire Ireland squad on Saturday and the Sunderland player apologised for his action.
Learning from mistake
"I'm able to laugh about it now and we're able to joke about it, so it has helped integrate me I suppose," he said.
"It's the greatest honour to play for your country and that's where my frustration came from. It was stupid.
"It was idiotic but I'm human and it's over and done with now. I've learned from it."
McClean remained in the Ireland squad for their friendly international against Oman in London on Tuesday, and came on as a second-half substitute in their 4-1 win.
Over and done
"I was just delighted to get on the pitch considering what has happened on this trip," said McClean.
"I'm just glad that it's all over and done with now. It was nice to get on and the fans were amazing.
"They've taken to me from day one. They're a great bunch."
Ireland will take on Germany and the Faroe Islands in their next Group C games in October.
