How can I compete as F2P against full P2W/Mech abusers?

How am I supposed to play against these so-called top players, who only have a full pay-to-win squad with Xabi Alonso QC?

All they do is spam passes with their insanely overpowered players, and on defense, they just rely on AI and second defender mechanics with nonsensical pressure that doesn’t even cause fatigue throughout the match.

What can I, as a free-to-play player, do? How should I approach the game? Or should I just accept defeat?
