Rangers are having a pretty good couple of weeks. Progressing through in the Scottish Cup, picking up a win over St Johnstone and a huge draw at Celtic Park, it's been a fortnight full of hope and optimism.

That's only been enhanced by the arrival of Pedro Caixinha, who has signed a three year deal to become manager at Ibrox.

Celtic supporters don't see his arrival as a threat whatsoever and you can see why. They're 33 points ahead of their arch-rivals right now, unbeaten against them this season, have dished out three beatings and are on their way to a sixth successive league title.

However, should they show such hubris? As we know these things can change quickly in football and there are a few reasons why things may not all go Celtic's way over the next few years.

Here are THREE reasons why Hoops supporters should write off the new Ibrox boss...

He's won major honours before

Pedro Caixinha has won major national honours before, with Santos Laguna in Mexico. In 2014 he won the national cup competition Copa MX and in 2015 went on to win a national league title in the second half of 2015 as part of a league and play-off format. He would also go on to win the prestigious 'Campeon de Campeones' match where the winners of the league in the first half of the year met his Santos Laguna side for a winner-takes-all final on neutral ground.

He clearly knows how to get results and get them in high pressure games. That winning mentality will bode well for Rangers.

While Mark Warburton had his positives, he had never actually won anything as a manager before arriving at Rangers and never won anything approaching the stature of the Mexican trophies while at Ibrox. In the end, it was perhaps that misunderstanding of the need to win every game that because his downfall.

If Caixinha can transfer his success with Santos Laguna to Ibrox, it could be a great few years for Gers fans.

The derby proved Rangers can compete

Part of the thinking around why Celtic shouldn't fear Rangers is to do with the gap that is already in place in Scottish football but perhaps the two squads are not as far apart as first thought.

The derby on Sunday showed that Rangers can compete with Celtic when the two sides meet, and that was at Celtic Park. If Caixinha's side can show they can match the Hoops on a regular basis then winning titles and cups really comes down to their performances and results against the rest of the Scottish Premiership.

Rangers have the second biggest budget in Scotland and should really have done better this season than they have done. They're being outpaced by Aberdeen and it's surely an anomaly?

If Caixinha can bring the side back to where they should be, it may not be as far behind Celtic as Hoops supporters think.

Pragmatism shines in Scotland

Pedro Caixinha is said to be a pragmatic manager, a far cry from the gung-ho Mark Warburton in his time at the club. That's what Rangers need right now, it plays to their strengths and more importantly gets results in Scotland.

Celtic are indeed playing some pretty pleasing stuff on the eye, but as Sunday's derby also showed, it can be fought against with physical and determined play.

Rangers have looked weak at times this season, a lack of tackling conviction, a lack of authority in the air. Caixinha will be looking to bring that back and put a bit of steely determination into his side.

Good football may come, but if the new Ibrox boss truly is a pragmatist then it can only bode well for the Govan side.
