The third player is a 23 year old left-back because Arsenal doesn’t have a left-back who can really attack and defend at the same time. After we all saw how Kolasinac can’t defend like a proper defender and is rather weak at the back, spending money on Jose Gaya, who can be a long-term option will be advisable.
After spending more than eight seasons in the La Liga already, he is really proving himself as a pacey left-back that can cross pushing forward and defend as well. The Spaniard has been one of the best players for Valencia in the past 3 seasons and is wanted by a host of clubs across the continent. Due to this, the Gunners will now want to add him to their squad as well, as he is really capable of making a major impact in the long-run.
