I thought you did a very good summary on what you viewed was required of a modern full back mate, however I disagreed with your assessment of Gibson when he played full back for England and us.Playing for England U17s as left back in the Euros when he was at Newcastle was the first time I saw him, and he stood out as very solid and reliable , just what was needed in a multi talented attacking team .
While I take your point about full backs needing to provide good attacking intent , the priority for me is that they are good defenders. Of the young players we’ve tried at left back , Garbutt, Galloway and recently Charsley all had a degree of attacking intent but none have yet convinced they could take over from Baines as defenders. Gibson has all the basics of a good defender, he’s young enough to develop attacking skills say to a moderate but acceptable level. At full back I would rather have a good defender/ moderate attacker than a moderate defender/good attacker.
I think he’s the most likely of our young defenders to provide cover at left back, and if he eventually gets that chance in the first team he’ll get great experience, and then eventually be able to fight for a CB position, which like you I believe will be his ultimate position . Holgate has gone a similar way.
I thought the three central defenders did well yesterday until the final minutes, particularly Foulds on the left of the three who some ,
@Barnfred 55 ? I think, have also touted for the left back role. It’s always good to read the different opinions on here.
