Chris Jack: Success is the only way that Rangers boss Pedro Caixinha will silence his critics in Scottish football

The Portuguese has wasted little time in making an impact in Scottish football. Whether his tenure as Rangers boss is a success or a failure, it is unlikely to be boring.

His straight-talking, open approach has already rubbed some in our game up the wrong way but Caixinha isn’t here to make friends and the Ibrox board haven’t appointed him to win a popularity contest.

If he can somehow lift the Premiership crown, he will be adored by the Light Blue legions, and that is the only section of the country where he needs a high approval rating.

It will take time for Caixinha to fully settle into life in Glasgow and for managers, supporters and the media to get a firmer grasp of who he is and what he is all about.

Having arrived from Al-Gharafa as a virtual unknown, he certainly has doubters to win over and critics to answer. Results on the park will never be lost in translation, though.

Caixinha is happy to talk tactics but there is a time and a place for chats about offensive transitions and moments in the game.

The aftermath of an Old Firm defeat at Hampden isn’t one of them, especially when your side has been outplayed and outfought. It opened him up to unfair ridicule in some quarters and the reaction to him moving glasses around the table was unsurprisingly over the top.

It doesn’t make for great newspaper copy but some supporters would quite like to hear their manager’s insights into what he is trying to achieve on the park. The medium has to fit the message, though.

Caixinha has ruffled a few feathers with his words and his actions in the last few weeks but being different isn’t a bad thing.

He was criticised for naming his starting line-up for the trip to Kilmarnock at his pre-match press conference as he revealed that David Bates and Myles Beerman would feature at Rugby Park.

It was an unusual move but it certainly wasn’t disrespectful and it had nothing to do with how the action unfolded hours later as the Gers were held to a goalless draw by Lee McCulloch’s side.

Rangers dropped two points because they didn’t play well, not because Caixinha had let the cat out the bag.

A couple of days later, he presented the written media with an A4 sheet of paper that listed the side he predicted Derek McInnes would field at Pittodrie that weekend.

Again, it was out of the ordinary as pressers go. But if a manager doesn’t have an idea of who he will be lining up against just 48 hours from kick-off then his preparation has to be called into question.

McInnes wasn’t going to work on his shape and system all week and then think ‘oh no, he’s on to us’ and change his plans after picking up his newspapers on the Saturday morning.

The latest public toing and froing between Caixinha and the Dons boss made more headlines this week and added a welcome bit of intrigue during the final days of a wretched campaign for Rangers.

Caixinha, apparently, broke the unwritten rules in Scottish football. His comments about Ryan Jack were positive and complimentary but he hardly set out a contract offer and said he was going to build his team around the midfielder next season.

Then he riled McInnes by saying that Aberdeen will have a renewed cycle in the summer. With Jack and Niall McGinn, and possibly others, heading for the Pittodrie exit door, Caixinha was right.

If the Dons are to be best of the rest again next term, new players will need to come on board and more improvement will have to be found as Caixinha attempts to haul his side up the Premiership standings.

His comments about the Dons were fair enough, as was the retort from McInnes when he stated that Rangers should be embarrassed with their performance in the Premiership. Few Gers fans will disagree with his assessment.

It all added a bit of drama to proceedings and Caixinha has given pundits and punters alike plenty of talking points so far. The more he provides next season the better.

His no-nonsense, honest approach is preferable to interviews about how everyone is ‘looking forward to the game’ and that the opposition ‘have good players’.

He is friendly but fiery and has shown that he can go on the offensive as easily as the defensive.

Caixinha will continue to do things his way. If he can get results on the park, he can say whatever he wants off it.
