Derek McInnes feels his Aberdeen side can keep the title race interesting after closing the gap on Celtic to just four points.

The Dons made the most of the Hoops' goalless draw against Dundee by beating Dundee United at Tannadice on Wednesday night.

Aberdeen have been criticised before for not making the most of their chances to apply pressure to Celtic, but McInnes is confident the Dons can sustain a challenge.

"It was important to win," he said. "We felt we needlessly shipped two points on Saturday. We were very comfortable with two minutes to go and gifted a penalty.

"When you see the players working so hard and are so committed, when they don't get the reward for that there was a lot of anger and frustration and it was important we showed that.

"The performance was good but the result was everything.

"We are just delighted with our work here and we move on with 10 games to go.

"We have a 10-game season and we are confident that we can win games that can keep everybody interested.

"We have been given every encouragement by the last couple of results.

"Hopefully I'm still being asked the same questions over the next few weeks, but we have to keep winning."
