Former Celtic midfielder Scott Allan on BBC Scottish football podcast "After Celtic conceded the second goal you just look at them and you don't really see a way back into the game. "That's the concern when they're playing against that level of opposition, once Celtic concede the equaliser, you feel that they're going to concede again. "That's the kind of way it is with Celtic in Europe recently. It ended up really comfortable for Celta Vigo." Former Celtic goalkeeper Pat Bonner on BBC Sportsound "I don't think Celtic are good enough, individually and collectively, to take on a team that's eighth in La Liga. "They moved the ball really well and Celtic couldn't get close to them. "They are not good enough at this level. Celtic are paying big money for some players because the fans are demanding it and then they come in and aren't good enough. Even Camilo Duran, is he good enough at this level?" The Guardian's Ewan Murray on BBC Scottish football podcast "I thought first half Celtic defended very well but second half it was like the Celtic goal just annoyed Celta. "Celta Vigo won 2-1, but they could and probably should have won by more."
