Arsenal are set to take on West Brom at the Hawthorns in what could be a thrilling Premier League encounter.
As the race for the top four heats up, Arsene Wenger's men cannot afford to drop points in the run of fixtures coming up. West Brom have problems of their own as they are currently on an 18-game streak without a win.
Here are three key battles that could decide the clash on Sunday.
3. Mesut Ozil vs Gareth Barry
Arsenal midfield maestro Mesut Ozil has been a man on a mission in recent weeks, proving to fans and critics alike that he is an important cog in the Arsenal attack.
His presence in attacking midfield will cause an array of problems for West Brom, who will need to counteract his attacking play. The man tasked with chasing around Ozil will likely be Premier League veteran Gareth Barry, who will need to be on top of his game to slow down the German magician.
2. Arsene Wenger vs Alan Pardew
Alan Pardew and Arsene Wenger have not always seen eye to eye, but there is no love lost between the two as they look to go to battle on Sunday.
The clash could ultimately come down to the tactical battle between the two managers, as their previous encounters suggest.
Arsenal will likely go on the attack early and look to apply pressure from the outset, leaving Pardew's side to adopt their familiar position of sitting back, soaking up pressure and hitting out on the counter-attack.
1. Alexis Sanchez vs Ahmed Hegazi
Alexis Sanchez proved why he is so hotly sought after with a magnificent brace against Crystal Palace in Arsenal's last game.
With the Chilean seemingly on his way out of the Emirates, many have questioned his commitment to the side - but he has shown that he can provide the impetus for Arsenal's attack when called upon and will look to do much of the same against West Brom.
This is something Baggies centre-back Ahmed Hegazi will need to bear in mind when Arsenal visit the Hawthorns this weekend.
The Baggies recently secured a permanent deal for Hegazi, and he will be looking to prove his worth to the West Brom faithful as they look to take on the attacking threat of Arsenal.
