Not really, if they elevate us into Europe. And especially not if they get us 4th.
if they don't get you to 4th then really you are back to square one next season. Different matter obviously if they get you a CL place but its still an awful lot of talent to replace just in Lukaku (think Barry will join permanently)
If Lukaku is the difference between them finishing fourth rather than 6th he would have made any loan justified with the revenue from the CL.
