What the pundits said about Celtic's draw in Bergamo
Former Celtic captain and manager Neil Lennon
"I think it's one of best results in Brendan Rodgers' career. They have proven tonight they can go away from home and dig out a result."
Former Scotland forward James McFadden
"Even the most optimistic Celtic fan wouldn't have expected a clean sheet at Atalanta. Celtic were far more narrow and compact [than the Dortmund game].
"It's a fantastic result, it really is. Liam Scales and Auston Trusty were outstanding. The two of them didn't panic. Atalanta asked a lot of questions and Celtic had the answers."
Former Celtic goalkeeper Joe Hart
"So many moments in that game it felt like the pressure was similar to the Dortmund game.
"Dortmund got out of control very quickly, but this time Celtic could deal in the chaos, win the big headers, got a little bit of luck, and some big saves from Kasper Schmeichel.
"Once it got through to 70 minutes it felt like Atalanta ran out of ideas. Celtic as a complete squad, brilliant effort."
Former Celtic goalkeeper Pat Bonner
"That was much more like it. Celtic got better in the second half. I thought they'd actually be under more pressure.
"They defended their box brilliantly. I've got to give credit to Rodgers and the staff, they got it absolutely right."
