On 25 March 2011, in only his second international, a UEFA Euro 2012 qualifier in Slovenia, Motta scored the game's only goal following a 73rd-minute combination with Federico Balzaretti. He was selected to the finals in Poland and Ukraine, starting in three group stage matches for the "Azzurri" and adding two substitute appearances, against Germany in the semi-finals (2–1 win) and Spain in the final; in the decisive match, after having again replaced Riccardo Montolivo, in the 55th minute, he suffered a hamstring injury after only five minutes and had to be carried off, leaving his team with ten players as he was the third and last allowable player brought in by manager Cesare Prandelli – in an eventual 0–4 loss.
