Celtic 2-1 Falkirk: What O'Neill said

Celtic manager Martin O'Neill tells BBC Scotland: "Delighted to win the game. The exertions and disappointment of Tuesday night, have to overcome that and travel back.

"The physical and psychological aspects of it all were big concerns today. Falkirk caused us umpteen problems in the game here last season.

"We created a lot of really good chances, but at 2-0 it's still on a knife edge. They get the goal and then the las5 15 minutes become a worrying time when perhaps it shouldn't have been.

"We go again on Wednesday and we'll see how the players are. A lot of the players that played on Tuesday started to flag a little bit and it's early season - the players are still getting up to speed.

"[Camilo Duran] played here [at Celtic Park] against LASK on the right-hand side and then it was seamless him moving to centre-forward. He was fantastic and he has been since he set foot in the football club.

"Hassan will cause problems in the final third. I think he will be terrific for us. I was delighted with his performance.

"Kieran [Tierney] I thought had cramp, but it wasn't. It looks similar to Kasper [Hogh]. I'm not sure at this minute - I need to find out from the medical staff how that is.

"I'm still really hopeful we can do something [in the transfer market]. If we want to defend our title and get something in the Europa League we need a bit more strength in depth. I think that's pretty obvious."
