Keita Balde Diao bagged a brace and provided the assist for Lautaro Martinez's header.
“The reaction was the right one, the team played sparkling and attractive football," Spalletti told Sky Sport Italia.
“We showed patience, because Frosinone are dangerous on the counter-attack, so it was better to keep them pinned back there and under pressure.
“It is very important to be calm in possession. The ball is still moved around quickly, but not frenetically, otherwise you have to work harder to chase them down and get it back.
“Keita has the ability to do remarkable things and was pretty consistent this evening. He only had a few moments where he dropped out of the game and at that point he becomes a burden the rest of the team has to cover for.
“I liked Lautaro's character, as he is physical, a fighter and never wants to let go. He'll battle to the last drop of sweat."
