Rangers travel to Pittodrie on Sunday, with the massively difficult task of trying to be the first side in over 10 matches to beat Aberdeen on their own turf.Derek McInnes' side are in excellent form and will fancy their chances of all but ending Rangers' quest to finish second in the Scottish Premiership this season. If they win then they'll go 15 points clear with just 6 games remaining.You may think that there'll be a bit of trepidation from Pedro Caixinha and his squad heading north to face the Dons but we reckon it could be just the ticket for the new manager given what's at stake.It's a chance for the Portuguese to show what his Rangers side are really all about after two disappointing draws against Motherwell and Kilmarnock.However, the Gers have only won one away match in 2017, highlighting just how big the challenge is.Here are THREE reasons why Caixinha should relish that challenge, not fear it...

Proving the doubters wrong

It's fair to say that in the wake of poor results at home to Motherwell and Kilmarnock, the doubters who were initially sceptical about Pedro Caixinha taking charge are even more so now.

Journalists like Graham Spiers have been quick to criticise the team, even calling the appointment of the new Rangers boss 'baffling' in recent tweets.

Getting a big win at Pittodrie would certainly shut people like him up and give the Rangers supporters a much needed shot in the arm.

It's far to early to judge the new manager at Ibrox, especially as he hasn't had a transfer window to work with, and even defeat against the Dons would tell us little about the man.

It's a case of nothing to lose, everything to gain at Pittodrie and if we were in the Rangers hotseat, we'd relish that opportunity.

A chance to show progress

Winning or even drawing at Pittodrie would offer tangible progress compared to Mark Warburton's reign at the club having been defeated by Aberdeen earlier in the season - the first match between the two sides in over 5 years.

They were sunk by a last minute winner to really give Derek McInnes' team belief that they can go on to finish higher than the Ibrox club this season.

A victory would be a clear sign that Pedro Caixinha is now getting more out of the players currently at the club that Warburton was managing, especially with so much now on the line.

Sunday's match is undoubtedly one of the biggest of their entire season and if there was ever a time to put in a performance then it's this weekend.

A win would make Caixinha something of a hero with the fans given there is no love lost between the two sides. It could be the goodwill he needs to enhance his authority over footballing matters at Ibrox.

Cutting the gap

Rangers are currently 12 points behind the Dons and are in fact closer to fourth position in the table than second. However, a win cuts that gap dramatically and with another match between the two set to be played at Ibrox after the Scottish Premiership splits, they have further chance of reducing that deficit.

Cutting it in half is within their own power and it could be enough pressure for the cracks to show in Derek McInnes' outfit.

No-one is really expecting Rangers to pick up a result on Sunday so with the pressure off and the chance to put themselves back in the mix for second, what manager wouldn't look forward to that chance?
