A double from Malik Tillman secured the points, but the manager admitted they could’ve added to the tally with a number of good chances throughout the 90 minutes.
Speaking to RangersTV at full-time, he said: “It was very comfortable throughout, but I'd like to see us score one or two more. I thought the keeper made a big save from James Tavernier early in the game and Ryan Kent had a fantastic effort off the bar.
“In the second-half I thought we were a bit stuffy at times, almost wanting to score the perfect goal. We were in good positions, but it was comfortable and it was really dominant with over 70 per cent possession.
“I thought Dundee United stuck to their game plan, but it was just a matter of how many we were going to score.”
The manager was happy with the impact of Malik Tillman, as he hailed a positive day for the squad.
He continued: “Malik hadn't played for a few weeks and then he scored in the last game at Motherwell, but it was important we got him as many minutes as we could safely and I thought he was good today.
“I thought him playing closer to Alfredo [Morelos] gave us a different presence up there in terms of being able to hold the ball and maybe get Todd [Cantwell] and Ryan [Jack] in the game higher up the pitch so all in all a really positive day and no injuries and a clean sheet for Allan on his 500th game.”
The win made it 10 wins in a row in the Scottish Premiership for the side, with Beale adding: “It is important the form, November was the last defeat, so it is a long time in terms of doing well in the league.
“We know where we are, we know we have got some big games coming up but all we could do today was win this one.”
