Level 4 player in my league?

[EmilZ]

Hey, I joined the game midseason and got pre-simulated some pretty bad results with which I was left 14th. I now have a great lvl 1 squad though (even a scout! Didn't buy tokens though), and am up to 4th. I just beat the first player in the league, but in the result, it says next to his name that he's level 4? But he's in my league and his players are pretty much average, 3, 4 and 5 stars. Can anybody explain why? Is this a glitch? The picture is attached
