FILIP HELANDER was frustrated Rangers couldn't add another clean sheet to their tally as they extended their unbeaten Premiership run with victory over Hibernian.

Steven Gerrard's side remain on course for an invincible league campaign after goals from Joe Aribo and Ryan Kent were enough to clinch all three points at Ibrox.

But there was disappointment late on for the champions as Kevin Nisbet headed home a Paul McGinn cross to deny Rangers another clean sheet on home soil.

Hibernian are only the third team, after Motherwell and Dundee United, to score on Premiership duty at Ibrox this term and Helander will look at the build-up to the goal as attentions turn to the Scottish Cup clash with Celtic this weekend.

Helander told RangersTV: "I think we controlled the game good in the first half and then started off quite well in the second half and got to 2-0.

"Then we conceded a goal and obviously that makes it harder. They get some energy and we had to really fight for it but it was a victory and we have got to be happy with that.

"Of course it was hard to take [to lose a goal]. We fight so hard to get that [clean sheet] and we didn't.

"We are disappointed with that of course but when you win that is obviously most important. Our victory record record here at Ibrox is nice.

"Most of the game we did well but when you concede a goal you can't be too happy about it.

"It is something that we have got to look at what happened there.

"Of course it is a big game [against Celtic]. There is one more title to get so we are looking forward to it.

"We have got to prepare well for it and hopefully we will get a good result there."
