Yeah 40k is gonna be a little too low for upgrades right now, but once you get coins I’d definitely try and upgrade the left back. Maatsen at 200k could be a nice option once you have enough coins
I would definitely say Drogba over Puskas, 5 star weak foot over 3 star is big, and Drogba has tiki taka playstyle so it’ll be a lot easier to pass and build up with him
