Motta struck the only goal of the Euro qualifier.
"I couldn't have asked for more than scoring on my second cap. I must above all thank the lads and Coach for giving me confidence and a warm welcome," he said.
"We played good football, which is what the Coach asked for, taking control in midfield and playing Antonio Cassano between the lines where he can put in through balls.
"Cesare Prandelli asked all the midfielders to move around and not stay static, as that makes it more difficult for Slovenia to defend against. We did that better in the second half and found the space we needed.
"I think we have to carry on along our own path, as we have a very strong squad that can certainly do better, but so far is also doing pretty well."
