1. You either got trolled
2. His players are on form and you just had a bad day...

PS you not the only 1 who gets a bad result, even though you have researched his past matches, got a perfect counter against his formation. Every manager goes through this, I mean I have bad days (well most days are bad) but I carry on and try and better my team. Dont stress bud, doubt its something huge! Nordeus wasnt on your side that day I guess
