Arsenal will face Chelsea this weekend in a clash between two new coaches who will bring two new styles of play, to their respective teams.

The midfield would appear to be the main area of overhaul for both managers, but it’s actually in attack where Unai Emery could face the bigger headache.

But is a nicer headache to have: Emery has to decide which of the massive attacking names at his disposal start, and which best fit the system he chooses to deploy.

Can he get all four mentioned below into the team? If not, who does he leave out?

Here are some of the questions Emery faces when trying to fit each of his four most potent attacking options into his side this season.

Pierre-Emerick Aubameyang

A lethal forward, the former Saint-Etienne and Borussia Dortmund goalscorer is probably the first name on the teamsheet, certainly amongst the attacking options. But where does he play, and who plays around him?

There’ll be a temptation to use his pace on the left or the right of a front three, but that could stunt the Gabon captain’s ability to score goals - after all, he is a central striker.

Alexandre Lacazette

Similarly, the temptation with Lacazette is to put the Frenchman up front and stick Aubameyang to one side.

The former Lyon striker could well be the one shunted to a wider area, which would seem to favour Aubameyang more than it would Lacazette. But is there a way in which Emery could fit both of his strikers in a system with two up front?

Henrikh Mkhitaryan

Any switch to a front two would presumably mean a diamond formation for Emery’s first season in charge.

That has the benefit of ensuring Arsenal’s width comes from full-backs, where Hector Bellerin can do a lot of damage, but it could also mean it’s harder to fit all four big-name attackers into the same system.

In a diamond system, you’d think it would be Henrikh Mkhitaryan who would miss out.

Mesut Ozil

Whilst not really an attacker as such, Emery’s first game in charge saw Ozil play in a front three.

With Aubameyang up front, Ozil and Mkhitaryan either side makes a lot of sense, but in a midfield diamond, could it be the German who makes way for the Armenian, who often played centrally for Manchester United in his first season in English football?
