All matches for Sevilla are easy ones except Barca and Atletico Madrid at home. So it's up to them to finish 4th.
Werder has 6 remaining matches. Some of them are really tough. For instance Borussia, Schalke and Wolfsburg away and Hamburg at home. Meanwhile, Leverkusen has only two tough matches: Bayern at home and Stuttgart away. Personally, I wouldn't bet on Werder finishing 4th.
In EPL there are three contenders for 4th place: City, Spurs and Pool.
4. Spurs 31 games played 58 pts
5. City 31 games played 56 pts
6. Pool 32 games played 54 pts
Pool will have to play Chelsea at home and Birmingham away. With their current form (no Lucas in the centre
) they can win 'easy' matches. So, if we think that Pool will lose to Chelsea, draw with Birmingham and will win all other matches, they will finish with 67 points. It means that Spurs need to win all their 3 let's say 'easy' matches: Burnley, Bolton, Sunderland; and get 1 point from other four (City, ManUtd, Chelsea, Arsenal).
