Lionel Messi thought Joe Hart's performance on Wednesday night was "phenomenal", Andres Iniesta opted for "outstanding" while Barcelona manager Luis Enrique described Man City's goalkeeper as "incredible".
The Spanish side won 1-0 in the Nou Camp to complete a 3-1 aggregate win over City, but the scoreline would have been much greater but for a string of saves from Hart.
"He was phenomenal, he stopped everything," Messi said on the Barca website. "We have to congratulate him on a great game because he's a fantastic goalkeeper."
Andres Iniesta added: "Hart was key to keeping them in it and was great in one-on-one situations. Outstanding."
Coach Luis Enrique was happy to see his side progress to the quarter-finals of the Champions League, but felt the scoreline did not reflect their dominance - with Hart the main reason.
"The score could have been a rout," he said. "Hart was incredible but we weren't really on towards the end.
England goalkeeper Joe Hart has said he has put his name down to take penalties if it comes to it against Italy. But he hopes it won't come down to that.
