Go away yourself and check some facts before you come out with garbage. He's had five full seasons playing for Boro not three.
If Gibson has genuinely turned down moves to top clubs because he's scared to move away from his family then he'll never make a top class player as that his simply not the right attitude. I doubt he has though.
I've never said he's not a good player, and I wasn't suggesting he'll never be an England player. The point (which seemingly sailed over your head like one of the passes teams would kill us with if we had this crab next to Keane) is that you were talking about him as if he's a player with potential, when the reality is he's basically entering his peak years right now, and is still playing in the Championship. He might go onto get 10 England caps, but I very much doubt he'll ever be a regular, because as well as the three I mentioned, you've now helpfully pointed out that he's also behind Tarkowski and Mawson who are the same age/younger.
If we were talking about paying £5m for him as a decent back up option i'd say good business, but he's absolutely not what we need at the moment. He's basically a clone of the defenders we currently have, and at the sort of fees being talked about would - in my opinion - be a continuation of the awful transfer business we have conducted in recent years.
I remember watching Gibson and RLC in the same game back in 2015, when the England U21s played at Oakwell.
Gibson partnered Stones at the back and I was impressed, but mainly in the sense - and I said this at the time - that he looked like a solid, decent defender in the Jagielka mould.
But, I don't think he's taken massive steps forward since then, and if he did come, I wouldn't want him as first choice. And, since I'd say we need 4 CBs maximum next season, then I'd rather the centre-back we sign be of real quality.
