Kilmarnock at Rugby Park really was the definitive game of two halves for Rangers manager Philippe Clement.

When Ibrox Noise saw his starting XI, we knew that was a ‘loss’. We did of course 100% back him publicly, that’s what fans do, but we knew privately he’d got it wildly wrong.

We’d warned about it, that this was a big test, his ‘first’ time facing Killie on their patch, their notorious patch, and that he’d failed the two other big league tests already, away at Dons and at Celtic park.

And we hoped this ‘first’ would yield better results – the man learns, he does.

And that XI was a dud. Yes, Ibrox Noise was also wrong about Borna Barisic, we made a mistake projecting him as an appropriate starter, but we were right about almost all the rest.

And when we saw Diomande, Silva and Cortes in the XI, we knew once again Clement had underestimated a big challenge and this was going to be a long night.

But, we also knew it was a HUGE test of his learning skills.

Would Clement realise his own errors and make the changes needed?

Not quick enough, true, by half time we were all over the place, and Killie were worthy of their lead, if not more.

But he made two changes at HT, taking off the very poor Borna and Silva, and replacing with Ridvan and Dessers, and while that didn’t have an immediate impact, it helped later.

And the big stuff was on 55 and 56 minutes. Tavernier’s inspired free kick along with getting the ineffective McCausland (another one we sort of got wrong on Ibrox Noise) off and replacing with the vastly-superior Dujon Sterling.

From there on in Rangers were massively improved, and that’s why Clement doesn’t start with his strongest XI – he leaves some key players to bring on later if his ‘weaker’ side isn’t working.

And this is where the learning procedure accelerated – instead of Clement learning from his errors by the next encounter, this time he learned by about half time.

He made the changes over 10 minutes and that changed the game.

This is what a manager does – he sees what’s wrong, and he changes it. He didn’t have his shining hour that first 45, but like a pro-active boss, he makes those alterations.

Sure, we’d have done it earlier, but we’re not the manager.

First half fail, second half big win.

We’d have taken that before kick off any day of the week.
