The UEFA Europa league is indeed a B-league, where one sees the teams that are simply not strong enough to make it in the Champions League. That said, the Europa League is not devoid of quality or entertainment, and one can look forward to semifinals where three Spanish teams will be fighting for the spoils:
- Valencia-Atletico Madrid
- Sporting Lisbon-Athletic Bilbao
Another succesful coach (and also from Argentina) is Marcelo Bielsa, who is doing wonders with the talented Basque side of Athletic Bilbao. They are in the Spanish Cup final and after eliminating both Manchester United and Schalke 04 (two teams who were coming from the Champions League) from the tournament, should be counted as favourites against Sporting Lisbon.
I would put money on a purely Spanish final.
