James McClean admits his Twitter rant was "stupid" and "idiotic", but he also thinks it may end up helping his Republic of Ireland career in the long run.
McClean received a dressing down in front of his team-mates on Saturday after venting his fury on Twitter at not coming off the bench during Friday's 2-1 win over Kazakhstan.
The 23-year-old deleted the foul-mouthed tweet and made a grovelling apology that saw him retained in the squad for Tuesday's friendly against Oman.
Trapattoni's grilling of McClean has made the player the butt of some light-hearted jibes during training since, and stand-in captain Kevin Doyle also revealed the squad were thinking of making the midfielder do a second initiation song as a forfeit.
McClean admits he was foolish to post the tweet, but he also thinks the friendly ribbing he has got from his team-mates has helped him become closer to other members of the Republic squad.
"I'm able to laugh about it now and we're able to joke about it, so it has helped integrate me I suppose," McClean said.
"It's the greatest honour to play for your country and that's where my frustration came from" - James McClean
"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."
The Sunderland winger impressed when he came off the bench for a 30-minute cameo, going close with two brilliant efforts - one a tricky volley and the other a superb curling free-kick that was saved by Ali Al-Habsi.
McClean looks like he will have to spend more time on the bench though after Trapattoni revealed that he would not start next month's qualifier against Germany in Dublin.
But the former Derry City man is just happy that he still has an international career, and that he still retains the support of the Republic fans, who gave him an almighty cheer when he came off the bench after an hour's play.
"I was just delighted to get on the pitch considering what has happened on this trip," McClean added.
"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."
McClean is part of a new generation that Trapattoni seems reluctant to throw in to the full team for this World Cup qualifying campaign as he vows to stick to his trusted group of experienced players.
David Meyler, Robbie Brady, who scored one and set up two more on debut, and Seamus Coleman all seemed more than capable of raising their game to international level on Tuesday, albeit against a side ranked 53rd in the world, and McClean thinks this bodes well for the future of the squad.
"Robbie Brady is a great lad," McClean said. "It's not bad to get a goal and two assists on your debut.
"I'm glad David and Seamus got a game too. The future looks good."
O'Neill says ordeal getting ridiculous
"Genuinely, we can have a laugh about it first of all, but now it's getting a bit ridiculous." - Martin O'Neill
However, Black Cats boss Martin O'Neill has revealed the Twitter matter will be discussed further on his return to Wearside and the player will be told in no uncertain terms what is required of him.
O'Neill said: "James has been acting rather strangely. It's good when the player not only wants to play, but he also wants to manage the team as well.
"James is rather young for that at the moment. I think Mr Trapattoni has got a couple of years on him and a couple of titles too in front of James, so I think he's entitled to pick the team.
"He has even admitted himself he has been rather foolish. He has taken himself off Twitter, apparently then he might have a situation with Facebook as well and about 14 other accounts that he has.
"He has a bit of a problem and we will have to rectify it. We can have a bit of a joke about it and laugh about it and think: 'Well, that's okay'."
Referring to his club's policy on such matters, he added: "He does know the rules - they were read to him, they were given to him, he was there that day - and not only that, some of his language was pretty poor and we will have to deal with that.
"Genuinely, we can have a laugh about it first of all, but now it's getting a bit ridiculous."
