Celtic manager Martin O'Neill has named his team to face Rangers this afternoon.
The Scottish Premiership champions come into the Glasgow derby after successive losses.
Celtic were beaten at Ibrox in the Premier Sports Cup last Sunday and Ferencvaros won 3-1 at Parkhead in the Europa League on Thursday evening.
From that defeat to the Hungarians, O'Neill has made three changes to his starting XI today. It appears Celtic will play with a back five against Rangers.
The 74-year-old knows his team must respond after a difficult week.
"We need to start on the front foot and not get too frustrated with it and try and create some chances in the game and see if we can get the first goal," O'Neill said on Friday. "That would help as well, but not to panic either at the same time if Rangers score first, which they did in that big game at Celtic Park [in May].
"It's a big game whether it's played in September or March. It's a really big game. And do we need to win the game? It would be nice to win. It wouldn't be great if we lost. That would be three on the trot. But we need to be up for it."
CELTIC STARTING XI: Sinisalo, Donovan, Carter-Vickers, Trusty, Scales, Tierney, McGregor, Baur, McCowan, Nygren, Duran.
SUBS: Johnstone, Hogh, Tounekti, Oxlade-Chamberlain, Hassan, Mheuka, Murray, Forrest, Ralson.
