Enda Stevens made his senior Republic of Ireland debut on Saturday, as Martin O'Neill's side beat the USA 2-1 at the Aviva Stadium.
Stevens was introduced as a 77th minute substitute, as Alan Judge scored in stoppage-time in Dublin and Stevens admits it's a moment he will never forget.
But the 27-year-old is focusing on a second season in the Championship with the Blades now, after impressing last term following his switch from Portsmouth.
He remarked: "It's been class with Ireland, since the first day I met up with the squad for the game in Turkey, the lads have been brilliant.
"It's just one big group and hopefully I've impressed enough in training and my appearance at the weekend, but now my focus is back on the Blades."
Stevens added: "I'll be relaxing now for a week or two, then hopefully hit the ground running in pre-season."
