I think because their season has been as poor as ours in the PL but they have still won two trophies, as well as qualifying for the CL, leaving us the only top English team not in it.
Also, any club managed by Mourinho deserves all the contempt they get.
He spent over 100m last season and now he has qualified fir the CL, he will spend even more in the next transfer window.
They might have finished behind us in the PL by one place, but I'm sure Mourinho will be grinning smugly at Wenger, as he passes us, and goes above us next season.
With this win they are a club very much on the up, like spurs Liverpool, Chelsea and Man City.
We are going in the other direction.
