The Serie A leaders put in an insipid performance in the Groupama Stadium and face a struggle to maintain their European ambitions alive.

Maurizio Sarri has slammed the pedestrian passing of his Juventus gamers as they fell to a 1-0 defeat to Lyon at the first leg of the Champions League last-16 tie.

The Serie A leaders were insipid in the Groupama Stadium and had no response to Lucas Tousart’s solitary strike in the 31st minute.

Cristiano Ronaldo huffed and puffed in the attack, but was helpless to stop Juve finish the game with no registered just one shot on goal.

Sarri cut a frustrated figure and says he was amazed at how slowly his side moved the ball compared to the way they did in training before the game.

“It’s hard to explain why, but in the first half we moved the ball too slowly so that the resistance were going to press, win back the ball and score,” he informed Sky Sport Italia.

“We lacked aggression and determination when attacking and for 15 minutes lacked it defensively too.

“The second half was better, but it is inadequate to get a Champions League match. I don’t understand why I can’t get the players to understand the value of moving the ball quickly.

“That is fundamental. We’ll continue working on it and sooner or later this notion will get in their heads.

“I chose to tell them and there were many who had been doing this, moving the ball too slowly and consequently getting into the incorrect positions.

“We had training yesterday and the ball was moving twice as fast as it did tonight. This is the reverse of what should occur. Lately, we are doing plenty of things contrary to in training.

“When the ball is slow, you lose rankings, you permit the opposition to shut you down, to be competitive and steal back the ball.

“I do not even believe the Lyon pressing was strong. We just moved it never varied the tempo, and when you do that, it’s unlikely you are going to make anything.”

Juve defender Leonardo Bonucci gave a similar assessment of his side’s performance, stating”something was not switched on” throughout the match.

The Serie A leaders will have the opportunity to atone for their mistakes in the return leg in Turin on March 17.
