This again?
We have money regardless of Eriksen's sale. You get a big chunk for reaching the CL final, we have Europe in the bag again for next season, and we've barely spent a penny for the last couple of windows.
We may well sell Eriksen but it has nothing to do with the Ndombele signing. If we sell him then we'll sign another player to replace him, right now from everything we're hearing there's still a chance neither real/barca are interested and he may stay at the club.
We don't need to sell assets to sign a player for 60m this window, at all.
