Great football game! I did notice that sometimes, when a lot of players are bunched together, minor graphical glitches occur, like here for example in my screenshot, when the players were running off the pitch, at the end of the match.
It's a good point, multiplexor glitches are unavoidable in a crowded area but the players causing the glitch are being drawn in the border. The next version will fix this and also the players all bunched up before a penalty shoot out.
