If rumours were to believed we wanted to bring Mainoo a couple of summers (or was it last summer?) ago.
We were well aware of his talent despite having only played youth football. He'd now be in our first team.
Likewise I'm sure we were aware of Wharton before he moved to Palace, but we wanted to see if he could step up.
He has, as has Mainoo. If we sit back and let someone else in we risk missing another target that could fill the midfield void.
Yes ideally I'd love to see if he kicks on again, but he could cost us even more if he does or he goes elsewhere this summer.
Had we bought either at that point, I would argue your take that they would be in our first team now. They'd be on loan at Girona, or Celtic. And eventually sold to Southampton.
