It depends also on how the user plays. For example, I have a relatively big squad (currently, 28 players) and I use a squad rotation system. I used the weaker ones against weak opponents where I do not feel the extreme need to play the best 11. But, as we move furthur in the season, the best players will play more often to maximise chances of winning all competitions. But, for sure, this is a costly system in terms of tokens and club money. Also, given how the game functions, there is always the need to have young players in some positions for the future as these might not appear in the auction list later.
But, yeah, looking at his squad, he overdid it in terms of attacking wingers.
