Juventus coach Andrea Pirlo admits he's frustrated with their slow starts this season.
Ahead of their Champions League clash with Barcelona, Pirlo revealed he has not been happy when some of the players aren't 100 per cent focused on matchday.
He said, “I don't especially like it when some players approach the match and aren't at 100 per cent. But it's also given by the number of games they play and the mental fatigue.
“Maybe a spark is needed to make them perform at their best. It shouldn't happen but it's normal because we are in a particular period.
“It's difficult with many trips and this can happen. For matches like the one tomorrow night, however, it will certainly not happen."
Pirlo admitted he has been 'very satisfied' by French midfielder Adrien Rabiot.
“I'm very satisfied with Adrien. He's having a good season. I didn't know him that well. He's a hard worker.
“You have to think that he's at 70 per cent of his potential and can do more. He can become a great midfielder at world level."
