From that camera angle, it is difficult to make that call. You have to be in line wit Stern to really determine if he offside.
Bad calls happen all the time. In all sports there is always the feeling that a team or an individual gets all the good calls (e.g. ManU, Michael Jordan, Australia etc.) and some get bad calls (e.g. Lara, Viera, Rodman etc.). Once it's not blatant and calculated, you just have tuh get on wit de game. Personally, I doh feel it have no kinda conspiracy. If we play de blasted game wit some purpose and heart, we eh goh have tuh study dem ting. We shouldn't be banking on de referee. In de EPL, dem managers always complaining about dem referee. Is jes part of de game. Goals score, dey say it eh score. When it eh score, dey say it score.
