Five players that Arsenal could sign from other Premier League clubs
A few weeks ago it looked a certainty that Aguero would leave Manchester. However, a turnaround in form following an injury to Gabriel Jesus who had displaced the Argentinean in the team has meant that Aguero could well stay.
If he does become available though it is hard to think of a player that would improve Arsenal more. He is one of the very best strikers in the world and despite a poor injury record, he would be worth the risk.
A player of his ability does not move clubs too often. He is a better player than almost any player linked with Arsenal in the past decade.
