Not only Real Madrid will face quite tough opponents this week. Because it looks like Barcelona and Atletico Madrid also have equally tough opponents this week. Barcelona will face Real Sociedad, while Atletico Madrid will face Bilbao. So we can conclude that the three top teams currently, namely Barcelona, Real Madrid and Atletico Madrid, will all have tough opponents this week. And these three teams will really have their strengths tested by their respective opponents.
It's just that I'm pretty sure Barcelona will succeed in winning the match against Real Sociedad. Meanwhile, regarding the Atletico Madrid vs Bilbao match, I have a little doubt. Likewise with the Real Betis vs Real Madrid match.
Betis is still weaker than Bilbao and Sociedad, but yes, all opponents will have strong opponents and we can again see changes at the top of the table. I admit that Real may get the opportunity to change places with Barcelona in this round if Flick cannot beat Sociedad. I would not bet on these matches, maybe only on the match with Atletico, I think that both teams will score, and I expect Real to beat Betis.
