Rangers face the unenviable task of having to beat Celtic this Sunday if they are to progress through to the Scottish Cup Final in May.

As everyone knows, the Hoops have gone the entire domestic season unbeaten and with a just a few more wins will go down in history as one of best Celtic teams of all time. The Light Blues, of course, can stop all of that talk with a supreme performance this weekend.

Pedro Caixinha has restored a bit of steel and bit of pride back into this Rangers team, which was careering out of control under Mark Warburton before the Englishman's departure.

However, the upcoming match at Hampden is his biggest test and Gers fans will get a great sense of what the future has in store for them over the next 12 months when the referee blows the final whistle on Sunday afternoon.

How does he get a result? Who does he play? Which are the key areas of the pitch?

We answer it all in our how-to-guide to beating Celtic this Sunday...

The Big Return: Hodson in for Tavernier

James Tavernier is arguably the best right back in Scotland, in an attacking sense, but as we know Rangers may well be on the back foot this Sunday and that's where his weaknesses lie.

His positioning can be dire. He's found himself out of position, ball watching and generally at sea for large chunks of the season and if the Hoops turn up with an attacking flow at Hampden, that could well be curtains for Rangers' Scottish Cup bid.

Bringing in Lee Hodson worked at Celtic Park when Tavernier was unavailable and Pedro Caixinha should be looking to match that performance as closely as possible this Sunday.

He managed to keep Scott Sinclair very quiet in that March match and as we've seen many time this season, when you nullify Sinclair, Celtic are half as effective going forward.

This is a switch that could have a key bearing on the outcome of the match.

Focus on Dembele

It's safe to say Moussa Dembele is not at the peak of his form right now. After a stretch of games where he scored an incredible 12 goals in 6 matches for the Hoops, he now has failed to find the net in his last four, starting with the draw that Rangers earned at Celtic Park.

There are reasons for that, limited minutes due to an injury is the main one, but he looked pretty ineffective from the start of the match against Ross County last week.

However, it would be a danger to switch Rangers' attention away from the young Frenchman, even though he's not firing on all cylinders.

As we've seen many times already in his short Celtic career, he's a player who thrives on the big occasion and could punish the Gers massively at the national stadium if he even senses a hint of a suggestion he's getting a bit of space in the final third.

He is still the key attacking threat to shut down and that requires a massive performance from whoever the Rangers centre-back duo is.

Ensure Beerman has support

Myles Beerman has still only played a handful of matches for the Gers and while he's coped with the tests thrown at him so far, he's not faced anything like a motivated Celtic side.

He'll be up against James Forrest or Patrick Roberts on the left hand side of the Gers defence and that could be bad news with both having the pace and trickery required to expose his lack of experience as a professional footballer.

It's going to be absolutely vital that Pedro Caixinha instructs his midfield, most likely Jason Holt to protect the young left-back on Sunday. Adding more cover to that area of the pitch will help him cope with the Celtic threat, at least in the initial stages, as he grows into the fixture.

The last thing Rangers need is to concede an early goal, making an unlikely task almost impossible.

Play everything through Miller

Perhaps the most important thing Rangers do on Sunday is realise the importance of Kenny Miller in this fixture. He's reliably scored against, or even for, Celtic in this derby for years and years. He clearly loves hitting the headlines when an entire nation's gaze is on one match and you wouldn't bet against him finding the net at some point on Sunday.

The Gers must ensure he is on the ball as much as possible, even if it means deviating from their usual team focused game plan. He's the key to victory and if he gets a chance he will put it away.

He's already scored against them this season of course, putting the Gers ahead in the New Years Eve match. He also played a big role in Joe Garner's goal in the 5-1 game.

As we saw recently against Aberdeen and Partick Thistle, he's in peak scoring form, also having the experience and mentality to produce the goods when the pressure is on.

Feed Kenny Miller consistently over the 90 minutes and he'll get the job done.
