Why do you want a massive squad? Going 3 or 4 players deep at every position is rather unnecessary. Especially when several, if not all of them, will lack the required quality for the level. Its just courting an unhappy squad as some of them won't get as many matches as they want.
I have multiple injuries some for a good few months so I have bought players to cover multiple positions... Also the players I have I can play 4-3-2-1 / 4-1-2-2-1 / 4-4-2 / 4-2-3-1 so I am covered for playing one of the big boys or a game I think I should win. I have been lucky to get two championship teams so far in the league cup so I've played squad players to get them a game.
Pascal Kopke in German second division only 2-3 million, stats are not great but he is a goal machine especially if you put him as ADVANCED FORWARD. I've signed him and he has scored over 20 in Bundesliga, Premier League, and in Serie A. View attachment 1147468
