Country: England
I think that's one of the reasons Arsenal is looking at Fraser, who may not be the perfect player but who can add some quality and PL experience while leaving room in the budget for others. A young player with lots of upside like Claude-Maurice could back him up and be developed along with Nelson and Martinelli.
I think Umtiti is a lot more likely than Konate (virtually no chance of that), assuming Umtiti passes the physical exam, because I think they want some experience to lead the back line. Saliba could be brought in to be developed to eventually take over from Sokratis/Koscielny, along with Holding.
But whoever they ultimately go for, it's going to be an interesting summer.
Why do you think Konate is unrealistic? I hope we stay very clear of Umtiti now.
