An Arsenal-supporting friend of mine has been in a season-long sulk - not so much because Arsenal are in the wilderness at the moment, but because he fears Liverpool will go undefeated and "take the Invincibles season away from us. That's all we have left!"
For the record, while it is certainly possible, I doubt Liverpool will do it. They still have to go to Man City, for one thing. There is a reason only two teams have ever done it In English top division football (with a shout out to Preston North End 1888-1889, the original Invincibles). I do think Liverpool will finish the season with substantially fewer draws than Arsenal did in 2003-04 (13), though perhaps not fewer than Preston's Invincibles managed (just 4, wow!).
No, I'm not in a season long sulk re Liverpool - that sort of outlook is self-defeating, to my mind.
Good luck to them if and when they win the Premiership.
I'd rather salute excellence where I find it.
Re Arsenal, my frustration, (rather than a sulk) lies with the fact that the well known issues of lapses in concentration, lack of mobility, and focus, (and possibly, fitness) in that notoriously porous and brittle defence are not new, and have not been seriously addressed for the best part of four years.
