Celtic manager Ronny Deila has said that he expects next weekend's Scottish Cup semi-final against Inverness Caledonian Thistle to be a "tough game" after the clubs drew 1-1 in the Scottish Premiership.
Leigh Griffiths scored in the third minute only for Edward Ofere to reply a minute later to reduce the Bhoys' lead at the top of the table to eight points with seven games remaining.
"[The cup final] is going to be a tough game," Deila told Sky Sports News. "They are number three in the league. Few have done it (win the treble) before and you see why, it is difficult.
"You have to be up for every game and be ready. It was shown today that the game on Sunday is going to be even and we have to be really up for it."
Celtic last won the Scottish Cup in 2013, while Inverness are looking to lift the trophy for the first time.
