Celtic crashed to a 4-1 defeat at the Estadio da Luz to a rampant Benfica side and have now lost both of their opening games in the league phase.

However, Danish international Bah - who netted the second goal of the night - was impressed with Celtic's battling spirit after the interval, having found themselves 3-0 down at the break.

He said: "You could see Celtic's quality in the second half.

"Although the scoreline was 4-1 to us, I certainly didn't think it was an easy game.

"In the first half, we just tried to play our game and we did that very well.

"I think you have to praise the whole team for that performance in the first half.

"Even the strikers were working hard to close Celtic down."
