Celtic manager Ronny Deila has his eyes on a domestic treble after leading his side to Scottish League Cup glory following a 2-0 win over ten-men Dundee United at Hampden.

It was the first trophy of Deila's Celtic career after he joined the Glasgow giants from Norwegian side Stromgodset in pre-season.

Kris Commons opened the scoring in the 28th minute before United's captain Sean Dillon saw red for a reckless challenge on Emilio Izaguirre in the 56th minute.

Substitute James Forrest added a second in the 79th minute before Radolaw Cierzniak saved his weak 86th minute penalty.

"It's a great feeling. It's good to get off to a good start when you're the manager of a big club like Celtic," Deila said.

"This was the first trophy we could win and we did it. It gives you an appetite for success and you want more.

"I'm happy for the boys and I'm proud of them. I think they put on a professional performance today so we should really enjoy this moment."

The win, Celtic's first in the competition since 2009, is the 15th time the Glasgow giants have lifted the cup and keeps them on course for a domestic treble.

Only two managers in Celtic's 127-year history have ever won a clean sweep but Deila is hopeful of repeating the feat last achieved by Martin O'Neill in 2001.

"We have talked about this many times. It's a dream. It's so tough to do it, but it's possible," the Norwegian, whose side face United again on Wednesday in a Scottish Cup quarter-final replay, said.

"The dream is still alive and I'm happy about that."

Deila came in for criticism at the start of his Celtic career following an exit from Champions League qualification and a string of disappointing domestic results.

However, the Hoops have since rallied and have tasted defeat just once in 2015.

But while admitting the win helps give him some breathing space, Deila insists he can't afford to wrest on his laurels.

"I think it helps in giving me more time and space to create the things I want to create," the Celtic manager said.

"For me, it's not the trophy that has given me the most energy and enjoyment. It's the statement that we've done something right.

"It's a good day and I'm very happy for the boys and the whole team around them and it makes us more hungry to keep on working with the things we are doing.

"But you can never rely on what you did before.

"I said to the players that what you did last year is forgotten tomorrow so the idea is always to be ahead and try and achieve new things.

"Today I am happy and I'm going to celebrate we have a trophy and no one can take that away from us. But tomorrow we have to start thinking about Wednesday again."

United manager Jackie McNamara was left frustrated at some of Bobby Madden's refereeing decisions.

"I thought a lot of things went against us today but I'm proud of the players and how they responded," McNamara said.

"We stuck to our task and went right to the end despite the disappointments and set-backs we encountered and I can't fault the players for their effort and commitment."

United were temporarily reduced to ten men when Celtic opened the scoring as captain Dillon was off the park receiving treatment and McNamara admitted he made a mistake by delaying bringing on a replacement.

"I was about to make the change as it seemed to be taking too long and it proved costly at that point for us," McNamara said of Dillon, who was later sent off in the second half.

"He was getting stitches and I would like to see the challenge again that caused the damage to his leg, which they ended up getting a throw-in from.

"He's got a bad gash on his shin and I'd like to see if the challenge was a fair one."
