The way I see it is the situation is similar to when Sven and Hughes came to the club, they had to throw money at players if we were to have any chance of success. History tells us it doesn't always work of course, but this is Pep.
Pep arrives when many of our players are getting passed their sell by date at worst, hugely underperforming at best. He has to get results quickly but has little time. We have the money and he knows the players who will improve us. Amounts paid are irrelevant as long as we get his man.
Added pressure was put on Pep, I think, by Khaldoon who said that Pep would utilise the Academy players. I can't see this opportunity arising much in the first months due to the time constraints, with Pep working on educating the first the first team who stay with us and his new recruits.
