Celtic interim boss Martin O'Neill tells BBC Scotland: "To get a reception like that was really great, I must admit. Really, really great. Obviously I was delighted to win the game, relieved. I thought we could have put the game to bed earlier. It was a nervy sort of finish at the end but we won.
"But it was lovely to get that sort of reception out there 20 years after leaving the club. It was pretty special out there.

We had a tough time physically against Midtjylland and to win in Feyenoord was reminiscent of some of the old days we had before. Winning at Easter Road was big for us on Sunday. Third game in six days, so that was big for us to win tonight.
"I get great help [from the coaches and backroom staff] and that goes for everyone at the football club. The bottom line of all of this is: not only have they done it, they've made me feel very young. Which I'm not.
"If [the new manager] asks my opinion on the players, I will give it to him. I'll give him an honest assessment. It'll be nothing but a lot of praise for the players. What I think about them is they've really stepped up. Restoration of confidence was important. The goalkeeper has made some really important saves for us. The two centre-backs have been terrific. The captain has been a real leader.
"My family came up to the game tonight. The very wife who said, 'you'll probably mess it up'. I'm going directly to her to say I didn't. Do you know what she'll do? She'll remind me I did, in Midtjylland."
