Charlie Adam is calling for Rangers to show more consistency in the second-half of the season as they try to chase down leaders Celtic.

The Ibrox club currently sit nine points adrift of the champions having squandered points against the likes of Livingston, St Mirren and St Johnstone earlier in the campaign.

Adam believes that Rangers can follow Celtic’s example by developing a clinical streak.

Speaking exclusively to Ladbrokes Fanzone, he said: “There’s one word to describe Rangers so far this season, and it’s 'inconsistent’.

“Performances have not been at the level we’ve come to expect from them.

“Fans will have expected them to fly out of the traps this season and have a go, but we’ve just not seen that.

“Ange Postecoglou has got Celtic in a great position; some of the stuff they’ve played over the last two seasons has been exceptional, and if there’s one word you can associate with them this season, it’s ‘ruthless’.

“They’ve just found another level, time and time again. Even if it’s scoring goals in the last few minutes to turn one point into three, it’s something Rangers haven’t had.”

Since the appointment of Michael Beale in November however, the side remain unbeaten, collecting 16 points from the 18 available. A 2-2 draw at home to Celtic has proven to be the only negative in what has been an otherwise positive start.

That form, coupled with Sunday’s extra-time Viaplay Cup semi-final victory over Aberdeen, has given former Rangers midfielder Adam cause for optimism.

He said: “Things have changed in the dugout now and they’re starting to look like their old selves.

“Ryan Kent and Alfredo Morelos seem to be getting back to their best, and the team managed to get to another cup final last weekend.

“That’s where they want to be, winning trophies and clawing things back to how they were a couple of years ago.

“It’s a huge job, it’s a lot of pressure but Michael knew that when he took the job on.

“He knew the situation, and I think if they can get in a couple of signings between now and the transfer window closing then we’ll see.

“Celtic are in the driving seat at the moment, but these things can change quickly in football.”
