Manutd fan, you should know, that guy shares an studio with an equally obsessed Inter fan (who gets all bitter if Milan wins), their paid to be that way (that's part of the fun, you won't see Crudelli all happy about Inter winning in Europe), they show it and say it clear, Crudelli Milan fan, the other one Inter fan... those english commentators, well I'm willing to bet, were not Tottenham fans nor are they paid to act as Tottenham fans.
Also this is not an international broadcast, where you should keep it as impartial as possible.
If you may, watch italian SKY or even Berlu's Mediaset, those guys keep it as professional as possible.
