Joshua Barrie and Jonny McFarlane answer your questions from social media ahead of the big game.

Would you still pay £5m for Malik Tillman? (Stevie)

Joshua Barrie: Yes. Tillman has probably been this side's best performer, in what has admittedly been a poor season, during his first full professional campaign. Not only is it important to consider how the young US international will improve with a better-functioning team around him, but we should also consider where he'll be as a player in one or two years' time. How many are the finished article at 20? I agree with the statement that Tillman needs to impact Old Firm games more obviously but last weekend's defeat against Aberdeen perfectly demonstrated the outcome bias that can be used to judge performances. Despite creating a plethora of chances, the loanee faced plenty of criticism. In paying for Tillman, you’re investing in potential, not just quality. And on the basis of what we’ve seen so far, that should make the transfer a no-brainer.

Morelos' scoring record is dire this season but Colak can't get a game despite his goal-to-game ratio. Is this a failure of Michael Beale not being able to incorporate the player? (Charlie)

Jonny McFarlane: Not for me, Colak has barely been available due to various injuries and when he did get back fit and sharp, he was given a chance. He gave a decent performance without scoring against Kilmarnock at Ibrox and was readily talked up by Beale post-match. When he scored a double at Easter Road in the next game it looked like the Croat was on course to become the obvious first choice but he was genuinely dreadful against Motherwell in the following game and rightly dropped. While he's a good finisher he tends to drop out of games and I'm not sure he's really Michael Beale's cup of tea as a striker. I'd expect him to move on in the summer as he does have a tangible record of success in Denmark and Croatia while he will point to a decent goals-to-games ratio in Scotland. He's certainly a player from whom Rangers can recoup a transfer fee and his recent switch of agents to CAA Stellar suggests there might just be legs in this theory.

Could we get much more from John Lundstram as an aggressive no.8? (Ross)

Joshua Barrie: It's something Giovanni van Bronckhorst trialled at points throughout his time at Ibrox. Lundstram has an engine that can carry him box-to-box and therefore, watching him play the methodical No.6 role can feel counterintuitive. In reality, at home the type of space that would allow him to thrive higher up the pitch is rarely on offer and for the time being, Beale seems to favour him in a deeper role, where he can drop into form a back three with and against the ball to give Rangers superior numbers deep in the pitch. In a game like Sunday's, you’d imagine there will be more opportunity for Lundstram to use his energy than the last meeting at Hampden when Rangers sat back and played to contain. Hopefully, as was the case in a 3-0 win over Hearts at Tynecastle, that allows the midfielder to put in a performance like those which earned so much adulation last season.

Davies or Souttar next to Goldson? presuming he makes it (Jamie)

Jonny McFarlane: I'm picking John Souttar based on form at the moment. Davies hasn't been at his best in Old Firm games this season and his error for Kyogo's crucial second at Parkhead was comic cuts defending. Davies can play out from the back well and is a calming presence but you need to show personality in the big games at Rangers and he's yet to impose himself when it counts. Souttar has also made mistakes but has a bit more stature about him and I think he's the one Beale can be more confident about.

If Goldson is fit do you think there is a chance we will lineup with a back 3? (WBRFC)

Joshua Barrie: 

I think it’s unlikely on the basis of the most recent Old Firm game. In the build-up, Beale’s side managed to bypass Celtic’s aggressive press at points, instead of being exclusively restricted to playing over the top of it. This offered them more control than they'd enjoyed in previous visits.

From goal-kicks, they’d sometimes work the ball wide and get their midfielders making this run down the side. I'm not sure an extra centre-back is required with the ball to beat the press.

Where this point does hold greater merit is when defending crosses. Celtic have repeatedly scored goals by way of wide rotations and low crosses into the box and more often than not, they manage to get one of their midfielders into the penalty area quicker than opponents can compensate.

Notice, in the below clip of Kyogo’s opener at Parkhead, O’Riley runs off the back of the visiting midfield. It’s still a three-vs-three in the box but the midfielder's movement pulls both Souttar and Ben Davies out of position.

Rangers’ plan out of possession generally worked last time out and that was built upon aggressive positioning against the ball. They won’t want to keep a three-vs-one at the back as that will impact their press. However, Beale will know his side must up their game when defending low balls into the box.

When do you see McCrorie getting a chance in goals to show what he can do? (Ewan)

Jonny McFarlane: It's certain Robby will get a chance as Beale has mentioned it multiple times to the media. Rangers need a certain amount of homegrown players in the squad and he fills an obvious hole for next season. Can he be the new no.1? That would be a huge ask but he can make a strong case for himself over the next four or five league games if he can get fit enough to start. I'd wager that his role next season will be as a number two to an experienced international keeper who will be brought in to replace Allan McGregor. I believe that individual will be Jack Butland, who is currently on loan at Manchester United.
