it's weird that they beat Manchester United in Old trafford but then lose against Getafe who are struggling in relegation zone, maybe they got a little tired and played less serious, after 2-1 i actually made a bet on over 3.5 goals and thought it was an easy win.
It was a match of two different competitions
The win against Manchester United is the opening match of the Europa League, considering that next week Sociedad have a Europa League match so I'm not too surprised by yesterday's result against Getafe
The we can see the lineup of players yesterday in the match week 5 of LaLiga is different from when Sociedad met Man United.
