Deila: Caley draw shows treble will be hard
Ronny Deila insists battling Inverness showed Celtic in their hard fought 1-1 draw at the Tulloch Caledonian stadium that the domestic treble is still a long way off.
Returning Hoops striker Leigh Griffiths opened the scoring for the visitors in the third minute only for his Caley counterpart Edward Ofere to level just over a minute later.
Home keeper Dean Brill, back in the side for the first time in 11 weeks after recovering from a knee problem, dislocated the same knee in the 15th minute after being closed down by Gary Mackay-Steven and was replaced by Ryan Esson.
He denied the visitors on a couple of occasions and with the draw, the Scottish League Cup winners went eight points ahead of Aberdeen at the top of the Scottish Premiership table. Following their league game against Kilmarnock in midweek, Celtic face Caley in the William Hill Scottish Cup semi-final showdown at Hampden Park next weekend.
The Celtic boss said: "It is going to be a tough game. They are number three in the league. Few have done it (treble) before and you see why, it is difficult.
"You have to get 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.
"It was a disappointing performance. It is disappointing to lose a goal right away.
"There was a lack of energy and we were always a second too late in the challenges and didn't get the tempo or create the chances we wanted to, even though we had a lot of possession. One point is what we got, we have to make it right on Wednesday."
