If the club was thinking of bringing in Gabriel, they wouldn't have extended Mari.
Best case scenario, we go for him next season to compete with Mari for that LCB role when Luiz deal would've expired
Yeah that's my initial thought and what I think will happen, the extending of Luiz and signing of Mari sured up our CB's for next year.
That being said though, clearing out Sokratis, Holding, Mustafi and loaning Mavro means we can bring someone else in. Let's say Gabriel for instance means we'd have Luiz + Saliba RCB, Mari and Gabriel LCB.
