Kris Boyd insists Rangers have been impressive under but they will need to go to "another level" to win the Scottish Premiership.

The Light Blues ran out 3-1 winners against Ross County last time out to tie Celtic at the top of the table.

And while Boyd is delighted at the Ibrox side's current run of form he feels they will need to improve even more to get the title over the line.

Writing in the Scottish Sun, he said: "Philippe Clement has dragged Rangers back into the title race from nowhere.

"Now the Ibrox boss — and his players — need to find another level if they want to end the season as champions.

"Given Rangers’ recent form, some people might say to me, ‘What are you talking about?’.

"They have 46 points from a possible 51 in the league since Clement arrived, and currently have all the momentum.

"But champions kick on at this stage of the season.They find another level, no matter how consistent they’ve been.

"Rangers have been good — now they need to be even better. That’s life at the Old Firm.

"With 13 games to go in the closest title race in years, any slip will be costly.

"What Clement has achieved at Rangers in the past four months has been unbelievable.

"By the end of Michael Beale’s reign, this Ibrox squad had been written off.

"Now they’re only behind Celtic on goals scored at the top and have a chance of a Treble.

"It could yet be a monumental, historic season."

Boyd also insists all the pressure is on Celtic, with Brendan Rodgers' men having surrendered a healthy lead at the top of the table.

"There is now pressure on both teams —but moreso on Celtic," he continued.

"There have been problems off the pitch this season with fans going for the board, and they’ll be furious if they lose the league after being in total control.

"You can just imagine the atmosphere today if Kilmarnock manage to frustrate Celtic for any length of time.

"It’s a 13-game league now. What happens at Parkhead tomorrow afternoon will have an impact on McDiarmid Park at Sunday lunchtime."
