1) We have no need to, the stadium revenues give us a huge leeway in terms of FFP. What holds back our spending is available capital, not FFP, and the reports are Levy is looking for investment to enable us to do just that.
2) Who would we even sell for profit? Skipp would bring in the most, maybe 10-15m. Much better to give these guys some time on the pitch which will raise their values. Wouldn't surprise me if we have a good 5 academy players worth 20m plus come the end of the season, so long as Ange plays them.
