Seville are one of there 4 successful clubs.
To use Celt a Vigo and Villarreal who both got beat by an English team sort of strengthens the point. Especially considering it’s in a competition English teams have no interest in.
We’ve had good runs in it also but so have other clubs but using the Europa league as a baromater of how strong La Liga is outside there 5 top clubs and then saying Celta, Villarreal and Athletic have had good runs just confirms it’s actually not that strong.
Liverpool, Arsenal, United, Leicester, Chelsea, City and Spurs have all had good runs in the Champions Lge. That’s 7 clubs reaching the latter stages of the big one in recent years despite the tougher domestic schedule.
