I think the Ayling figures are probably accurate. He was a key player for Leeds when he signed that last deal. I doubt we'd pay half of that. Although I guess if it's for one season and no transfer fee it levels itself out.
I'd be stunned if O'Brien is on 'only' 15k a week.
Forest paid a fair few quid for him. Although I guess 15k would be a significant payrise to what he was on at Huddersfield. So maybe. I would have expected 20k-25k.
I would imagine 15k is within our budget. CM is an area where we have to invest. O'Brien is a decent age and a good longterm option.
