I think that Manchester City is a big club that can buy any player that they want but I don't know why they didn't go for some top players instead is even letting their top players leave maybe as you have said there may be some financial crisis in the club.
It could be more than just a financial issue, but rather a longterm strategic one. Manchester City often adjusts its squad composition to maintain balance, both in terms of player age and playing style. They're sometimes willing to let go of big stars to make room for younger talent or players better suited to Pep Guardiola's tactical needs. So, their move may be more about maintaining team continuity than simply stockpiling top players.
@SLAAAYYYYYY, you might be correct with your thoughts on the situation with Manchester city, it just can't be a financial problem because they're a big team with oil rich owners. The prospect could be more like not getting things right anymore and the club seemingly needs a transition in the management to get back into their game strategically. I am beginning to think that Pep Guardiola is starting to lose confidence with last season's setback, after covering himself in glory for a few seasons in a row.
