Ronny Deila has admitted that he felt under pressure this season as Aberdeen chased Celtic for the title.

The Hoops effectively won their fifth successive Championship last weekend with a 3-1 win over Hearts at Tynecastle, but Deila has accepted that he was made to sweat as Celtic headed towards the line.

A win tomorrow afternoon over Aberdeen at Celtic Park will formalise the Hoops' title party but it will also provide an opportunity for Celtic to show their superiority over an Aberdeen side who have beaten them twice so far this term.

"We want to win on Sunday, that’s important, to show who is the best team in Scotland," said Deila. "We have beaten them every time at Celtic Park since I have been here so we want to finish it off in an even better way with three points.”

"They have had a good season, they have pushed us, maybe more than they did last year as well even though it was quite close although in the end we had 17 more points. Hopefully we will again get a lot of points ahead between now and the end so it’s important to win on Sunday.

You never know in football and I never took anything for granted. Of course when I saw our performances, when we were not at our best and I didn’t see the progress that I wanted and have talked about before, then of course you are more worried than you would be if you were playing like we did last season. I wouldn’t have worried if we had been playing like we were at the same time last season because we were so consistent and we played at a very, very high level. It has been a little bit different this year, we haven’t reached that level but at the same time we have been quite consistent in the results.

"When you are a coach you are always worried. You don’t think ‘they have no chance’, of course they have a chance. The players, everybody, knows that. But in Celtic you have everything to lose and nothing to win and that’s a very difficult situation to be in. But I think the boys have handled that well. We have won important games and we haven’t lost in the league since Aberdeen. So even though everything has been so bad we haven’t lost since that moment. We are quite consistent results-wise and I think the Hearts game in the first half was a step in the right direction.”

And Deila believes that Aberdeen will be capable of keeping Rangers in the shade next season when the Ibrox side are playing in the top flight.

“I think it’s going to be close," he said. "I think Aberdeen if they can keep their consistency will be even better, if they can get more experience and maybe get another couple of players as well. They are doing positive things. It’s important that Celtic improves into next season as well. If not, they could be closer. But Celtic are the best team, now, and they have advantages over the other teams when next season starts.”

Scott Brown and Dedryck Boyata will miss this weekend's game against Aberdeen, but Stefan Johansen and Charlie Mulgrew are both fit.
