Your opponent played a illegal formation by the looks of it and you probably didn't pick a tactic or formation that goes against it too well, hes probably put all this players in the middle of the pitch and put 3 strikers on and played with either 2 defenders or a missing wing player, basically craming all the players into a key area of the pitch and blocking you out from scoring and taking full advantage, If you post the teams starting 11 and teams formations I maybe able to give you a better idea and understanding whats going on. It is possible for illegal formations to draw or even win but they normally lose matches.
