I love that you can still take some advantages of being a major club in this version. I'm in 2020, managing Bayern, and Mönchengladbach is hot on my tail with only 6 games left of the season. I started bidding silly bids for ALL of their players, which (obviously) got rejected. However, more or less every single player in their squad got upset and their form turned around in an instant.
Been doing that since FM13, and it's so great if you've been dominating a league for a few years. I remember being United, bidding for every Chelsea, Arsenal, Liverpool and City-player all season long, causing their teams to end up mid/below mid-table
