Re: Chelsea goal
It looked over to me (just) but there's enough doubt not to give it. The benefit of the doubt should go to the defending team-no way could the linesman have been 100% certain it was over the line so he shouldn't have given it.
In summary, it was over the line but shouldn't have been given because the officials must have been unsure.
Also, the fact it's even debateable after watching it on many replays shows TV won't always be a cure all remedy.
Actions, not words.
