Ezri Konsa completed his £55m move to Arsenal on Friday (Getty) On Friday, Arsenal also completed the signing of Ezri Konsa in a £55m deal from Aston Villa. ‘We needed one more player, we had seven players in the defensive line, we know that that’s not enough. We have two long-term injuries, one with Jurrien, and one with Willy,’ Arteta told Sky Sports when asked about the decision to sign Konsa. ‘And we wanted someone that didn’t have the qualities that we already have, so somebody ideally with experience, because as a centre-back in this league you cannot play jokes, we know how important that position is, and I think Ezri brings a lot of qualities that we needed.’ Comment now Comments Add Metro as a Preferred Source on Google Add as preferred source
