GREG DOCHERTY reckons Rangers have found their stride at just the right time ahead of a crucial week of Scottish Cup and Premiership action.

Graeme Murty’s side made it five wins on the spin as they eased to a 4-1 victory over St Johnstone on Tuesday night.

James Tavernier set the Light Blues on the road to success with an early penalty before Josh Windass, Sean Goss and Alfredo Morelos also found the target.

Rangers have now turned their attentions to their quarter-final clash with Falkirk on Sunday as they look to move one step closer to a return to Hampden.

And all eyes will then be fixed on the third Old Firm showdown of the campaign as Murty’s side attempt to keep Celtic in their sights at the top of the table.

The outcome of both games could decide what Rangers’ ambitions are in the closing weeks of the campaign and Docherty is pleased to be building up a head of steam before the run-in.

He said: “The cup is a big one and then Celtic straight after that doesn’t get any bigger.

“So for us we have got to take each game as it comes, this one is out the way now and got the job done.

“We focus on Falkirk now and we know it is going to be difficult, I know a few of the Falkirk boys and know they are good players.

“They will want to come to Ibrox and impress but we have got to go and do the job and I am confident we can do.

“I think momentum is a big thing and we are gathering that at the moment. We just want to keep going and if we can take this momentum into every game then fantastic.

“We just need to keep building and it is great for us to bounce back after the Hibs disappointment with five wins. That is big for us.

“The manager and the coaching staff have got us set up correctly and we are all just loving playing football at the moment.”

It was another pleasing 90 minutes in Perth for boss Murty as his side turned in an impressive performance to see off the Saints in style.

But Rangers are sweating on the fitness of winger Jamie Murphy after he was forced off late on with a foot injury.

Docherty said: “Jamie has been huge for us and he has helped me settle in well.

“He is a big player and he has got his own aspirations to get in the Scotland squad. I don’t see how he can’t on that performance.

“He is the best wide man in the league in my opinion and he has really shown that in the last few games. Obviously we hope it is nothing serious and we get him back for the weekend.”
