When do you swap out a regular?

At what point do you fold your hand and go with another option?

There are many different variables to consider, but Unai Emery has a choice on his hands if he maintains his current stance on formation;

Keep Pierre-Emerick Aubameyang in the striker role?

Or go with Alexandre Lacazette as our number9?

The clamour to start both players in the same eleven grows with each match. Both are bona fide world class players, and both have their own specific set of skills that when combined, would result in opposing defenders not having much rest.

With Aubameyang, his electric pace beats the majority of those who face him. He also has a knack for positioning himself in the right place for a pass or a knockdown. Auba in the box is - usually lethal.

His first three games have seen 90% of his game come to the fore, but when it comes to the final act - putting the ball in the net, he has fallen short. To be fair, it won’t be long before he finds his scoring boots as he has previously shown in other seasons with other clubs. He never runs dry for long.

Which makes the decision to leave him out even harder for Emery.

When you have someone like Lacazette waiting in the wings however, it is an attractive alternative option.

Like Auba, Laca has also shown his pedigree. Hardly a slouch, Laca relies on his unerring finishing to prove his worth, and his ability to work a yard of space when defenders are hounding him make him very dangerous indeed.

Emery has the luxury of picking and choosing who starts when. The Spaniard is a big fan of adapting to opponents, which could see these strikers swapping regularly to fit the teams who face us.

Emery is also known to switch tactics regularly too, so there is still a large chance for both to play alongside each other. This would negate having to choose who starts when and where, and would also give us the edge over most rivals in terms of attack.

City have Aguero and Jesus, Utd have Lukaku and Sanchez, Spurs have Kane and Alli. Laca and Auba though, when in full force, would overshadow them all.

We just need a chance to see it. We have some less formidable opposition coming up than the ones we’ve faced thus far.

Is it time to unleash Auba and Laca? If not, will the Frenchman get the nod over the man from Gabon?

What a wonderful and perplexing problem for Emery to have.

Who would you opt for?
