BBC Sport - Celtic v Dundee Utd Clydesdale Bank Scottish Premier League Venue: Celtic Park Date: Tuesday, 22 January Kick-off: 1945 Coverage: Live commentary on Sportsound (810 MW) or online at BBC Sport Scotland. Live text at BBC Sport Scotland website. Celtic's Fraser Forster is likely to miss out with a stiff neck. Efe Ambrose is on African Nations Cup duty with Nigeria and Kelvin Wilson is suspended. Adam Matthews and Kris Commons are minor doubts, while James Forrest and Paddy McCourt are still out. Dundee United have midfield pair Stuart Armstrong (family illness) and Richie Ryan (hamstring) back after missing the victory at Kilmarnock. Defender Brian McLean is free from suspension for the trip to Celtic Park. Celtic assistant manager Johan Mjallby: "Usually when we play them they are very competitive and tight games. They have got plenty of good players that can hurt you so we need to be at our best. But it was very encouraging to see how the team performed at the weekend and hopefully we do the same tomorrow and it will be hard for Dundee United. Dundee United manager Peter Houston: "It's another big test. It will be a case of when we get the ball we have to keep it as much as possible. Ball retention is always important against a quality side like Celtic and it will be the same for this game. I'm sure that if we pass the ball like we can, we can do well. Kilmarnock get a lot of praise for being a passing team but I thought we did that very well against them at the weekend, and I'll be looking for my players to continue that at Celtic.
