Sporting knocked out Arsenal - the Premier League leaders! I'm not at all convinced Brighton would have done all that much better against them than Juventus... though admittedly Brighton aren't burdened by Allegri's cowardice.
The Caf tends to ridiculously overrate the Premier League.
Nah, the premier league throughout the league is at a much higher level than anywhere else. There are a few elite teams elsewhere, but nowhere has the quality throughout the rest like the prem. And Brighton especially have been brilliant all season. Hell, look at West Ham. They're a mid table team who are relegation fodder this season, yet they are favourites for the Conference League.
And yeah sporting knocked out Arsenal on pens and Arsenal's focus is on the prem, pretty obviously. Plus it's a cup competition, one off results happen. Generally speaking though, in terms of what the teams have shown as a unit, Brighton is far better than any other Europa League side and they're arguably as good as Newcastle and United this season.
Juve for example are 7th.. yes points deducted, but would be 3rd which is mediocre anyway there. Bayer Leverkusen are 6th. Sporting are 4th in their league and fully outplayed Juve. Chelsea fully battered Milan earlier this season and Juve isn't better than Milan (though of course one off results are hard to read into). They are in the Europa League because they aren't Champions League level, that's about it really, and not like they've impressed in the Europa League.
