The Celtic winger was unable to contain his disappointment after Tuesday's heavy first-leg defeat, lamenting mistakes that "you would probably get away with on a playground"
Ambrose only arrived back in Scotland on Tuesday morning, following Nigeria's successful Africa Cup of Nations campaign, and was included in the starting line-up after insisting he was fit enough to play.
Celtic are 100/1 to take the second leg of their Champions League tie with Juventus to extra-time Coral
Ambrose misjudged the flight of the ball to allow Juventus to open the scoring after less than three minutes, before missing Celtic’s best chance of the game with a free header as well as losing possession to Mirko Vucinic who tucked home the third goal and effectively ended Celtic’s chances of progression.
"Look, the manager picked [Ambrose]. The manager pulled him to one side and asked him if he was feeling okay. He said he was feeling brilliant," Commons said after the game.
"You know, if he wasn’t feeling okay, then he should have said so. If he felt good, then he should have put in a better performance."
Commons did not just focus his frustration at the centre-back though, he rued mistakes made by the entire team to allow Juventus to take a comfortable three-goal lead to the second leg in Turin.
The Scottish international added: "It was just very sloppy, individual mistakes. Something you would probably get away with on a playground, not in the last 16 of the Champions League.
"There are certain individuals who let the team down tonight. At this level, you clearly can’t afford to make mistakes. If you do, you end up coming away with a 3-0 defeat."
Celtic captain Scott Brown, meanwhile, focused his attention on Juventus’ physical tactics, with a number of incidents going unpunished by referee Alberto Undiano Mallenco.
He added: "Their defenders manhandled every single one of us. Anywhere else on the pitch, it’s a foul.
"They knew we were strong at set-pieces and strong at running, the only way they could stop us was to manhandle us."
