After successive disappointing draws against Hamilton and Dundee, Deila said: “I’m my biggest critic, but I’ve been in this game a long time and when everything is crazy around you, you have to stay calm.
“It’s a game of football. We have everything in our hands. The players here are winners and hate losing or performing badly and they wanted to show themselves from another side today.
“I’m proud of how they did it, it’s something we’ll build on and I’m happy for the players that they played the way they did.
“Now we are in our fourth semi-final in two years and that’s quite a good thing. Hopefully, we can get into the final without any red cards and kick on.
“We have to beat everybody to win the trophy and we’re eager for that. Now we have two games left and, hopefully, we can win it.”
