Agreed.
And I was of the opinion that ten Hag wouldn't select him this season based on the games he's missed in the last few years which has dented his own personal development as a CB/RB imo. But he was very highly rated when we bought him as a youth player beating out Liverpool for his signature and he was said to be the France u17s captain.
I think we should buy two CBs of the requisite level who can be part of the first team and hopefully utilise Kambwala as a rotation option similar to how Liverpool utilise Jarell Quansah with Van Dijk and Konate the first choice pairing.
I think if we can have the following four options (below) going into next season, then I feel we'll be heading into the right direction.
Martinez, Branthwaite, Diomande, Kambwala
