We sit two points outside the top seven and face fellow promotion-chasers Stevenage in a hugely important Sky Bet League Two clash as the race for the play-offs hots up.
And McGuire, 33, says there is ‘nothing better’ than being roared on by a large away contingent of Stags’ fans.
“If we can do, can we fill that back stand out? Because there’s nothing better, to bring the fans down,” McGuire said.
“I’ve been here four years now and when this place is rocking, it’s behind us. We could do with a 12th man on Saturday. [We want to] get as many people down there as we can so we can kick on.
“It’d be brilliant to get the fans down. I keep pushing on about it but let's get as many fans down there as possible on Saturday and be our 12th man and get us over the line.
“We always do [have a great following] but to get those extra bodies in there, fill that back stand, it would be even better for us. There’s nothing better than when you see 300/400 Stags’ fans behind you screaming and getting behind your team, there’s nothing better.”
The former Fleetwood Town man also echoed the thoughts of manager Steve Evans, who told the local media this morning that it is important to focus on ourselves, rather than the opposition.
“It is tight but I think we’ve just got to concentrate on ourselves. Onto Saturday, we’ll get a good training session today, a good training session tomorrow and we’re all looking forward to Saturday.
“All we can do is concentrate on ourselves, that’s all we can do. The desire in the dressing room at the moment is just to concentrate on ourselves, nothing else, nothing more.
“They’ve (Stevenage) surprised a few people this season and they’re up there for a reason but to be honest with you, I’d rather just concentrate on us, all that matters is us.
“There’s a great desire at the moment between the players and the management to get over the line and that’s what we’ve got to do.”
The Birkenhead-born tough-tackling midfielder hasn’t appeared for the Stags since our 0-0 draw with Cheltenham Town in early March, but insists that the most important thing is to achieve success as a club.
“When the gaffer ever needs me, he needs me. I think everyone knows that I step in, I do a job. It’s not about me; it’s about the whole team, it’s about the management, it’s about the club, it’s about the town trying to get together for Saturday and trying to get these three points.
“When you’re not involved, you can’t just spit your dummy out because I’m not in the squad. It’s for this club, we all want to achieve one thing and that’s to get in those play-offs. If we can get in those play-offs, not many teams will want to play us.”
