As much as George is a 100% committed player he has been as injury prone as McBurnie over the last few seasons, often missing large chunks at a time, but he doesn't get criticised for it due to his effort levels.
I'd rather give Baldock another year as he is a better defender than Bogle, who is a good winger but a woeful defender, even at Championship level. That would leave us with Curtis, who doesn't look ready for Championship level yet.
I have no problem with giving Bogle another year as a winger and play him higher up the pitch with Hamer and Arblaster, but forget it as a defender.
I can understand us needing to reduce the wage bill and George is 31 now, but we'd need to replace him long term and he would gain more in leaving to help him keep playing for Greece. So I guess sadly it's a no brainer that he has to leave.
