There is a dedicated football thread on this forum already, in case you hadn't
realised.

[LEN Teh Footy God's Footballodium]

Regarding MLS, I would say that fans appear to be thin on the ground here. I
can only watch selected highlights here, but usually pass on those in favour of
French or Dutch football. What I do follow of it usually comes from here alone,
although I find that petty things such as difference in terminology [OT, W/L/T]
and format [Conferences, lack of relegation] irk me enough to turn me away if I
do decide to watch any.
