I just don’t know.He was then asked by the reporter whether he would like that to be at the end of the season, therefore committing himself to the club through the January transfer window and beyond.“I think you’re asking a lot there at this minute of a gentleman who was happy enough to get coffees beforehand and now who’s suddenly stepping into this,” O’Neill responded.O’Neill said he learnt plenty about his side during the Europa League setback in DenmarkAFP“If you’re asking me, in a way, I enjoyed even tonight and I learnt a great deal.“It’s a very fine football side we’re playing against and we have to compete. In the second half I thought we did that.“I also think Sunday’s game emotionally and physically took a lot out of us and there’s no respite because we go again on Sunday against Kilmarnock.”O’Neill was again probed for hints on his future and was asked whether he was in constant discussion with the board.“No I’m not and I don’t really want to be,” he replied. “I just want to be told when my time is up.”A bruising defeat in DenmarkThree goals in eight first-half minutes condemned Celtic to their second defeat in four Europa League games this season.AFPCeltic conceded three goals in eight frantic first-half minutes[/caption]The loss sees Celtic slip to 27th in the table and outside of the top 24 places which would secure qualification for the knockout rounds.The Hoops face tough tests in their next two European outings with a trip to Dutch side Feyenoord before welcoming Roma to Celtic Park in December.“We expected it to be tough but we were well in the game with half an hour gone in the match and no score in the game, and then we conceded two goals within a minute, and then a third one within seven minutes,” O’Neill told Celtic TV at full time.“So, naturally that turns the game. We showed a lot of resilience in the second-half to keep at it because the team could have gone under at that stage but they showed a bit of character.“The side over the past few weeks has been going through a difficult period, losing some football matches, which is unlike the football club, and then you come here to a very difficult away game in European football and these things can happen.“By the time you try and refocus the second goal goes in and then there’s a mountain to climb, but these things we have to address – we have to address it domestically and try and see if we can improve with the European scene.”
