You're right, £40m porro + £30m Deki + Udogie + £40m Maddison + £16m GK is no different to signing N'Jie and Kevin Wimmer.
See what I mean about tunnel vision?
Transfer prices have increased significantly since when bought Wimmer and N'Jie. 30 or 40 million isn't that much when other teams we like to think we are competing against are spending double that.
