Gabby Agbonlahor was thoroughly impressed with Celtic during their 0-0 draw with Atalanta last night (Wednesday), and outlined what he reckons will be key for the Parkhead side moving further into this season's UEFA Champions League.

Speaking on talkSport this morning (via Celts Are Here), the former Aston Villa forward singled out Hoops stopper Kasper Schmeichel for his array of top-class saves on the night, while also praising Celtic's defensive wherewithal throughout the match in Italy.

"You’ve got to give a shout out to Celtic last night,” said Agbonlahor. “I watched the Celtic game at 5.45pm and they done the opposite of Dortmund when they got absolutely battered. They were more compact and throwing bodies in front of the ball.

“Schmeichel in goals was outstanding with some amazing saves. They showed grit, fight and defensive responsibilities. I am sure Brendan Rodgers will be so proud of them.

"They were just at it Celtic in the defensive part. Yes, they found it hard to get forward, but they were throwing their bodies in front of the ball."
