Two thoughts:
(a) In a way, we packed a full months of low form and what not into a night.
(b) It is a bit dangerous to take for granted that we will bounce back. Playing Spanish teams in Spain is not easy. Newcastle away is not easy. Brentford at home is not easy.
Winnable? Most certainly. Should we win them? Like if we play Betis and Newcastle away and Brentford at home 10 times, 30 games in total, we "should" maybe have what, 20 wins, 8 draws and 2 losses. But with bad luck, more injuries, we are out of form, you know -- it is not games that are "hard" to not win. 2-3 bad results, a bunch of injuries, suspensions and what not, and we have to play without key players, then this club face adversity for real. The top 4 spot starts to be in danger.
