That brings.back memories of the England u17 World Cup winners when Gibson was shunted out of the team by Guehi and Panzo who were , at the time bigger and more physical than Gibson. ( And Billy Crellin was on the subs bench for that team!) . Physicality is key for a CB these days, we’ve had the likes of Feeney, Welch, Astley recently who just weren’t big enough and good enough, as you say time will tell.….sounds a bit like Lewis Gibson coming through as LB/CB. It’s a difficult one because they look big in their age group and they’re all still growing, it’s usually easier to come through as FB but time will tell.
