Juventus boss Maurizio Sarri says defeat to Tottenham was expected given their fitness levels.
Juve lost 3-2 after ultimately being undone by Harry Kane's lob from the halfway line.
“It was a difficult game against a renowned team," said Sarri.
“They were quicker and more explosive, but they're closer to the start of their campaign and closer to the right preparation.
“We need to defend further forward and not so deep. We did better in the second half, with better pressure and 20 minutes of good quality.
“We were naive with the balls we lost, but I think physical condition also counts for something."
