It's not your fault , and Your Wifi 🛜 is also fine... So don't be upset
Sometimes the game feels unfair and Scripted... cause it's true... Because EA helps low rank and low ovr players sometimes to balance the game by helping them to win against higher ovr and Higher rank players...
You can't do anything about it... But yes you can do something to make it feels easy which I also do... Don't play 5-6 Head to Head matches back to back, keep patience have some rest do other things after playing 3 or 4 matches... Before play the game reboot your device once a day...make sure you don't have any app working on background while playing the game...
Use formation that have atleast 1 CDM and better midfield support....i personally use 4-2-3-1 Narrow... Use Players and formation that suits your own play style... And if you are conceding goals then take your time to build up the game by passing with your CM,CDM,CAM,ST... don't be hasty...and at the beginning of the match play passes with with your midfielders and Defenders to feel comfortable and to confirm that everything is working fine...
I hope it will work 😄
