Martin O'Neill has been speaking to the media as Celtic prepare for the Europa League match against Besiktas on Thursday (20:00 GMT).

Here are the key points:

• Fit-again Yang Hyun-jun has done "a little bit of training" and while Thursday's game comes too soon, O'Neill says the South Korea winger "definitely wants" to be involved against Kilmarnock on Sunday.

• O'Neill says he attended a Celtic Supporters' Club meeting in Greenock on Monday night as he wanted to hear what the fans are feeling and "see how we can do something about it".

• Nothing surprised him and he adds: "The questions are straightforward, I think you would know what they would be. I think they were fair and I think the board as a whole tried to answer them as honestly as they possibly could."

• O'Neill understands the fans' frustration but his job "doesn't depend on attending meetings, it depends on results".

• He admits it's trying time for Celtic, confidence is low and players have pointed out the similarities to when he came back last season.

• On whether he knows his best XI, O'Neill says: "No, I keep getting asked this question and until I know exactly what everyone can do at the football club then I probably won't know that. It's not always knowing about your best team because we've had a lot of games and we're rotating a bit as well to try and save some legs, save a little bit of energy."

• The Celtic manager insists the Besiktas game isn't must-win but concedes his team need to get off the mark in the Europa League after starting with three defeats.

• O'Neill believes his team are still capable of reaching the knockout stage: "If 10 points is the mark we are capable of still qualifying, but we're running out of matches."

• Besiktas are a "real handful" with so many quality players and are "flying" in the Europa League with seven points from a possible nine.

• O'Neill thinks former Celtic forward Oh Hyeon-gyu may have a point to prove on Thursday night, but says Celtic have something to prove too.
