Former Nigeria international Victor Ezeji believes Arsenal should be focusing on signing a defender in the form of Leicester City's Caglar Soyuncu instead of Thomas Partey.
Ezeji is in agreement with the Ghana international making the switch to England but insists that the Gunners should be focusing their energy on bolstering their defence.
“The problem of Arsenal has been in defence," Ezeji told Goal.
“Going forward they can score goals with the likes of [Pierre-Emerick] Aubameyang, [Alexandre] Lacazette and [Nicolas] Pepe.
"They can score as many goals as they wish to in any game but their problem has been defensive and I think if they can bring Partey there will stability in midfield and he will also shield the backline.
“Partey is a good buy no doubt, but Arsenal must do something to their defensive line," he added.
“If I’m to suggest they should go for a defender because their defence is very porous at the moment, [then] going for a player like Soyuncu is not a bad idea but that is if Leicester City are ready to let him go.
"David Luiz is not that bad, but his mistakes are very costly so they need someone that can put him on his toes.
"Sometimes players relax and don’t really have that motivation, but once they see competition they know if they flop, somebody else will take over from them, so they will put in their best.
“He will complement Luiz," the ex-forward added. "He has proven over time that he’s a very good defender. If Arsenal can go for him, he will definitely step up his game even more.”
