I don't think Liverpool would value him that highly; if they did, he'd have been in their squad this season.
He is 22 with no PL pedigree. He has potential, but is also probe to getting bullied out of games easily. I certainly can't see anyone shelling out 5m, let alone 10m, on a player that...
There won't be any Championship teams higher than us at the beginning of August (unless we get relegated). Although not likely, I really don't see this as an impossibility; we free up a load of wages this summer from the end of Kemy and CMS's contracts alone.
I don't think it's incredible. He's already 22 and has been at Liverpool for 3 seasons now. If they valued him so highly, they'd have had him in their squad of 25 for this year. Other than his loans at Brentford and for us, he has only played u21 football.
