Well butI am to blame for defeat

produced more passion yesterday. He went on: “They did it, totally.

“Maybe even the penalty comes from that situation – to look like you have passion but not know exactly where to place it in that exact moment.

“I wasn’t unhappy with Myles Beerman. It’s one decision from one young boy. I hope he learns from it.”

Caixinha waited for referee John Beaton at half-time and shook the official’s hand as he went down the tunnel.

It was a gesture straight from the methods of fellow countryman, Jose Mourhino.

Speaking about the incident, Caixinha said: “I just salute him.

“There will be a time where I speak about the referees. There will be a time where I speak about a lot of things.

“I’ve arrived here in Scotland and I’m assessing everything, not only my team.

“I need to know how to behave, regarding to all these situations.

“I’m here to defend Rangers and I will defend it, for real.”

The recruitment of new players will not be easy, as Rangers will not push ahead with building a scouting network until they appoint a Director of Football.

Caixinha said: “When I was interviewed for the job, one point of the presentation was a scouting department and the way I organise it.

“But it’s not one of the priorities for me right now compared to the work and assessing what I need to do – and the knowledge I need to get.

“We’re still trying to find a Director of Football and scouting will be more linked to him. We’re getting closer to appointing someone. People are being assessed.

“That’s not within my range but the club are assessing. So we have one month to re- organise and put all the assessments we’ve made on to paper.

“If I’m going to organise a scouting department as well, it will take a lot more time to bring what we want for next season.

“I have a lot of knowledge of players, clubs from different leagues and competitions. I know what I want and what the club needs. We’re working on it.”

Caixinha’s biggest success in football so far came when he won three trophies with Santos in Mexico.

He spoke about the way signing three Argentinean players transformed the fortunes of the team.

It seems likely he will again look to recruit players from around the globe.

Some fans of the Light Blues might already be having doubts about the manager, but he maintains is here for a lengthy spell and is moving his family to Scotland.

The veteran striker should have been celebrating a new one-year contract, but instead spoke of feeling ashamed by Rangers’ five-goal thumping

He said: “Disappointed isn’t a strong enough word.

“The boys feel ashamed to play a part in a performance like that.

“We’re embarrassed by the result.

“A lot was levelled against us last week about not getting close to them, not laying a glove on them.

“I wouldn’t say that was the same this time but ultimately it wasn’t good enough.

“The goals we lost were poor, as were the decisions which led to them. “It was all wrong. “We lost 5-1 in the first Old Firm game of the season and that was very similar.”

Miller has been one of very few consistent performers in Light Blue this season and is clearly hugely frustrated by losing five times to Celtic in one season.

The Hoops are 36 points clear of thirdplaced Rangers.

Some supporters showed how much they are hurting by throwing scarves at the pitch and leaving in droves well before time-up.

Miller went on: “I’m bored talking about us being more competitive or putting up a challenge. It’s just words.

“Next season, a lot of things need to be put right to put us in a better place.

“It’s not for me to say how many changes need to be made. That’s up to the club and the manager.

“He’s the one who’ll assess his squad and decide where he feels he needs to strengthen.

“But you just need to look at the league table. We seemed to get carried away as a football club by where we’ve been in the past.

“Aberdeen are well clear of us, so that suggests just how much work has to be done and how much better we’ll need to be next season.”

The 37-year-old stopped short of suggesting a clearout of players. But he looks at the way Celtic have improved under Brendan Rodgers and hope a similar formula can work in Govan.

He added: “You only have to look at Celtic and what a difference a few players can make.

“It’s not about signing a whole new team. There’s no proof to say that will be an answer.

“But Celtic are the prime example of the difference a few better quality players can make, and a few of the ones already there being rejuvenated.”

The striker did concede that some players will be moved on unless they can suddenly transform their performances.

He said: “All the players are fighting for their future.

“After any manager changes, he’ll potentially have different opinions on players. So every one of us is fighting to stay here.”
