Former Juventus chief Luciano Moggi was left uimpressed by Dinamo Zagreb on Tuesday night.
Juve enjoyed a comfortable 4-0 win in Croatia for their Champions League tie.
Moggi rapped: "I do not think yesterday's game was any sort of test for the Bianconeri.
"It was like a game against reserves. A lowly Serie A team is definitely stronger than Dinamo Zagreb.
"Juventus have produced a good game, but it didn't for count much. They took three points and that's it."
