Irish midfielder Willo Flood made an impressive debut for Celtic in the scoreless draw with Rangers at Parkhead on Sunday, then claimed the title is firmly in Gordon Strachan's grasp. Goalie Arthur Boruc was the hero for the Bhoys with a number of crucial saves as Celtic maintained their two point lead at the top of the table. Flood said, "I think a draw is still a decent result for us. It is up to them to catch us and if we keep picking up points then the league will be ours. "But, overall, I would have to say a draw was probably a fair result." The Dubliner was delighted with a surprise debut following his recent move from Dundee United. He told the Evening Times, "I was very surprised to be told I was starting. When the manager told me I was like, "yeah, are you serious?" "He told me to just go out and do what I had been doing for Dundee United for the last two seasons. It has been a long time coming, but it was good to get my debut over with and hopefully now you will see the real Willo Flood. "The first 20 minutes was intense and it was a bit faster than I had anticipated. Celtic is a huge club and the derby game is one of the biggest in the world, but you don't think about that when you're out there. "All you are thinking about is trying to play well and do your best for the team. I think my debut went okay." Celtic captain Stephen McManus praised Boruc, who pout his recent problems behind him with a man of the match performance. "He did really well and pulled off some great saves," McManus told the club's official website. "He did not have much to do before that, but we are lucky to have such a great goalkeeper." Rangers claimed after the game that referee Calum Murray denied Kenny Miller a late penalty after a clash with McManus. "Kenny Miller had an attempt at goal and it was a late challenge," manager Walter Smith said. "If it happens in any other area of the pitch then the referee gives the foul. "If it is in the penalty area then he has a couple of decisions to make and obviously he chose not to make them. As I say, Kenny had shot past and it was a late challenge but we never got it. "But we had a couple of other opportunities that Artur Boruc saved." Manager Strachan also praised Boruc and said, "He didn't have too much to do but he had two smashing saves. "He had a spring in his step and he made saves that he had been making for a long time. I liked what I saw." As for the two point lead Strachan said, "I would have been even happier if I was five points clear but I don't blame anyone bar ourselves." Strachan was pleased with Flood's debut and added, "I thought he did very well. Willo must be very pleased with himself."
