Yeah I agree. I'm not sure they would go as high as £50m at this stage, but I think they'd pay up to £40m. They may pay more than £40m if it included add ons but it's all guess work really.
I'd much rather pay that sort of money for a player like Barkley, particularly if he (as is looking likely so far) has an excellent season for us and is proven in this league. If you think that Wolves paid £35m for an unproven teenager, Newcastle £40m on Joelinton, and Spam £40m on Haller, the money we spend on Barkley will be much better value.
