A dramatic late Wesley Sneijder winner sunk Juventus in snowy conditions in Turkey and while Galatasaray boss Roberto Mancini thinks victory was deserved, he admits the game shouldn't have been played.
Mancini pulled off a shock triumph over compatriot Antonio Conte and progresses to the knockout stages, leaving Juventus to face a crisis.
The conditions made the game tough and after the final whistle Juventus officials complained that it should never have gone ahead.
"I thought it shouldn't be played today," Mancini told Premium Calcio. "It was dangerous for the players.
"The officials wanted to play and it was important for them to get the game finished."
Juventus had come into the fixture needing just to avoid defeat to secure second place with Real Madrid a long way clear in top spot.
