Ajax save what to do with all my money?

So I'm two seasons deep in my Ajax save. Have sold Frenkie de Jong for 85 million to Barca after 1 year and Ziyech for 85(100) to Chelsea just now. De Ligt will likely leave aswell this summer. What to do with all that money? Please help.

Invest in youth save some get the clubs finances up take players from dutch clubs so you're guaranteed the league every year and can focus on CL

Dump it into the club / youth system. I'm assuming different clubs do different things based on management but if you sit on it sometimes the board will make improvements without you having to ask. At PSV I got my balance to over 300M and the board made a bunch of improvements, including a stadium expansion immediately after we had just completed one, without asking. They weren't even board request options.
