We don’t know that, you’re making assumptions as I did.
For the price of Pogba and Lukaku he could have brought in B.Silva, Jesus, Sane and Laporte that might be slightly more expensive but it would be close. We also looked all set to but Griezman, the extra 100 mil that would have cost must have been there just twice he has turned us down.(if papers are to be believed)
I think there is money there and a willingness to spend it on the right players, hence intrest in Mbappe and Neymar recently with Neymars dad even being in supposed discussions with United. So for me there is cash there it’s just not wanting to over pay for players the board so on deem as worth it. So I think Pep would have been backed and probably built a similar sort of team to what he has, outwith D Silva, Aguero, KDB and Kompany, but he’s had intrest in Laporte since he was in charge at Barca so i’d Imagine that and probably Stones would have been in his plans.
Again all just wild speculation press rumours and stuff I’ve heard over the years. We’ll never know and I doubt he will ever manage at United now anyway.
