Mark Warburton leaving Rangers has caused quite the stir in Scotland. While the club's details of his departure seem to be disputed by Warburton himself, the fact remains that the Ibrox side need a new manager to take over from inexperienced caretaker boss Graeme Murty.

One of the names linked with the vacant position at Rangers is Aberdeen's Derek McInnes who has insisted he is focused on the Dons amid questions from the Scottish football press about the role.

As we know, things change quickly in football and it's unlikely that speculation around McInnes and Rangers is going to go away anytime soon. McInnes has taken a struggling Aberdeen and made them into consistent second place finishers behind Celtic in the Scottish Premiership, after all.

It's not like he's unfamiliar with Ibrox either having spent five years as a player there in the 1990s.

However, is this the step McInnes should take, or should he stay Aberdeen longer still?

Here are THREE reasons why he should not be tempted by the Rangers job...

Aberdeen are still the second best team in Scotland

If Wednesday night's thrashing of Motherwell proved anything it's that Aberdeen are most certainly still the second best team in Scotland, despite Rangers' promotion last summer.

Three points ahead of the 'Gers and with a vastly superior goal difference, it's clear that McInnes is maintaining Aberdeen's tag as 'best of the rest' behind Brendan Rodgers' Celtic.

Making the League Cup Final boosted those credentials too and with the Dons also favourites to make it into the Scottish Cup semi-finals, they could have more dates at Hampden before the end of the season.

That's got to be a positive for McInnes, who with an inferior budget is showing Rangers that there is no replacement for discipline, determination and team spirit in the Scottish top-flight.

Why leave Aberdeen when his best chance of silverware as a manager lies at Pittodrie? The future is bright at the club too with plans in place to build a new 20,000-seater stadium that could take the club to the next level.

Unfinished business

Reaching the next level? Aberdeen have been threatening to do that for years now under Derek McInnes but the club only have one Scottish League Cup to show for it.

That may have been their first trophy since 1995 but a club the size of Aberdeen should be at the pointy end of competitions every season.

In that sense, McInnes has unfinished business at Aberdeen. A much desired Scottish Cup will be at the top of that list but so will progression in Europe with a place in the group stages of the Europa League not beyond the realms of possibility.

Before Rodgers arrived there was even the hope of sustained Scottish Premiership title bids and while that may just be a twinkle in McInnes' eye right now, you get the impression it is his ultimate aim at Pittodrie.

The Aberdeen manager should only move on when he feels like that he's taken the club as far as he can, and he hasn't done that quite yet. He has the potential to be a Dons legend and leaving for one of their bitter rivals would colour that massively.

Unrealistic expectations at Ibrox

Whatever the scenario is at Aberdeen, moving to Rangers right now appears to be a poisoned chalice. There's no doubting that the Ibrox side offer one of the most prestigious roles in British football, but if it's a job doomed to fail from the start then is it worth taking?

Right now, expectations are still ridiculously high at the club with many supporters expecting, or at least hoping, they can challenge Celtic again in short order.

The reality is that could take years and unless a new manager can convince the supporters of that then they're going to be under immense pressure to deliver a success that might be unattainable.

What Rangers need is small steps and gradual forward progress, only then will they start to get to the top of Scottish football. Until the perception of fans matches that reality, it's a tough ask for any manager, not just McInnes, to achieve what they're hoping for.
