2) Alberto Moreno vs Hector Bellerin
Two of the most inexperienced players on the pitch. Moreno endured a difficult afternoon against Manchester United last time out, and will no doubt be eager to respond with a big performance here. He’ll be up against Bellerin, who at just 20 has been another impressive find for the Gunners. The Liverpool left and the Arsenal right will be free for these two to work up and down. Who does the best will be a decisive factor in the game.
