I'm guessing that you beat the team in 4th twice, and that 4th place picked up a win over Sophea and a draw with Leon. Once you take out points from games with Leon the table becomes:
Team Pl W D L Points
Sophea 4 2 1 1 7
Leon 4 2 0 2 6
Cruzados 4 1 1 2 4
Or alternately you scored a lot of goals in games vs de gea, and once those goals were removed ...
