MARK WARBURTON insists there is plenty of room for improvement for Rangers - despite seeing his side beat Hibernian for the second time this term.

A stunning free-kick from James Tavernier was all that separated the sides at Ibrox as the Light Blues moved six points clear of Alan Stubbs’ side in the Championship title race.

Rangers have now won six games on the spin under new boss Warburton as they have made an impressive start to the season and endeared themselves to Light Blues crowd.

A League Cup clash with Airdrie on Wednesday night is next on the agenda for the Gers and they are likely to have Lee Wallace available after he picked up a knock in the second half.

Arsenal starlet Gedion Zelalem could also be in line for his debut after he completed a move to Glasgow until January and watched from the stands yesterday.

And Warburton knows his side must up their game if they are to reach the high standards they have set for themselves this season.

He said: “To have a packed stadium and to get the right result and six wins out of six is of course pleasing, but we’ve got to accept we fell below the levels at certain times and we’ll analyse that and learn from it.

“The squad are keen to do that. It would be too easy to say ‘three points, thanks very much’ and move on. We’ll learn from it and hopefully be a better team for it.

“We were loose in terms of ball release and decision-making. We need to take care in the final third.

“We thought their game plan would be to sit in and hit us on the counter which they did on two or three occasions and it was through our sloppy play – we were too loose and made some poor decisions.

“But we had a good tempo for 10-12 minutes after half-time and Lee’s injury killed the tempo in a bizarre way and we never really regained it. But again we’re analysing a 1-0 victory here.”
