Even playing at their own backyard, Sevilla no longer got that 'scary' feel like before lah. Their mental is very stiff because they are fighting to stay in the league, so their playstyle is quite messy and easy to make stupid mistakes at crucial times.
On the other hand, Real Sociedad is much more steady. They are still chasing for European spots and even the Champions League ticket. The visitors are very good at controlling the game and their high pressing is very effective. Most importantly, they always makan goals regularly — already scored in 12 away matches in a row. Very dangerous one!
