Juventus coach Andrea Pirlo was happy after their 4-1 win at Spezia.

Cristiano Ronaldo came off the bench at 1-1 to settle nerves with a brace on the day.

"We played a good game, we should close it in the first half, we created a lot. If you don't do it you risk against any opponent," said Pirlo.

"We wanted to win it and Ronaldo helped us. We changed our system little bit, we knew Arthur would have been more free to play a little behind. Ronaldo is improving and we were waiting for him.

"Both him and [Paulo] Dybala are improving, let's see how everyone feels in the coming days.

"We always play with four defenders in the defensive phase. I had these players available, when everyone will be back we'll see how we can play but the setting will be the same.

"We are improving, some players are coming back from injuries and we'll have time to work on our ideas.

"Slowly, we'll see in games those situations that we are preparing during trainings. We need to pick up the players between the lines, once we do it, we only need to think about attacking their area.

"I'm trying to simplify the defensive phase with two tight lines, we need to be more aggressive once we lose the ball, it's less tiring to run five meters ahead rather than track back for 70 meters."
