It's just a random result similar to Stoke getting a win over Arsenal. **** happens, the equivalent to T11's troll results. It may not have been a formation issue before, but I am just highlighting where his weaknesses lie i.e central midfield.

When I lost league matches to lower Q teams, it always proved to be that the team is genuinely strong team despite having players with less stars. There was one who eventually finished 2nd in the league once. So I didnt think it was a troll result.

Lower levels, you can probably use the same formation for 2-3 season, but I am guessing as you go up higher, the same formation may not work eventually... everything has a breaking point. Just take it into consideration.
