Of course he did want to spend money. That wasn't the initial point. It was talk about him wanting Alvarez, Vlahovic and Diaz. Which isn't the case as he just listed them as examples. Of course he wanted to spent money, any sensible manager would. I am sure, you would too, right? Difference between Ralfs stance and yours maybe is that he would have went to bring in one or two established players and maybe 4 or 5 promising ones while you (maybe, I don't know) would try to bring in 3 very good established players for bigger money. When Ralf was around the team, it was obvious that many players wouldn't be around after the summer: Mata, Matic, Pogba, Lingard, Cavani, Greenwood as well - maybe add to that even Martial, Henderson and Bailley, so many departures will always affect team spirit AND more importantly that number puts Ralfs "up to ten players" (by the way he said "might be 6, 8, 10 players") into perspective. I am sure he was smart enough to know, that you don't do that all at once but.
100% agree.
I think, that is the essential part above specific names and numbers of new players. He knows that quality without hard work isn't all that much, a lesson quite a few fans don't understand as well.
