I agree that Real Betis have great potential to cause Real Madrid problems in this match. They will definitely try everything to make Real Madrid uncomfortable with their game. I think if Real Betis can keep Real Madrid's midfield out of action then they will be quite successful, yes they should come out with a strategy that strengthens their midfield. Up front, Real Madrid have a dangerous player and they can assign players to guard his movements, of course other players must also get attention.
It was a home game for Real Betis and I also have no doubts about the abilities that Real Betis has this season and Real Betis also drew against Real Madrid. But of course this should not be confused with this season where Real Madrid itself still has the ability and potential to beat its opponents so there is a possibility that it will be the home team that will make things quite difficult in this match. Although I also don't think that Real Madrid will win easily at home to Real Betis tomorrow.
Additionally, I think that Real Madrid will defeat Real Betis because their attacking players are excellent goal scorers and their midfield players will be strong because Modric will be in the starting lineup. If Modric is in the starting lineup, I think Real Madrid will win because he is an excellent passer of the ball to forward players. Even though real Betis is winning games and performing well, they will still face a formidable opponent when they play Real Madrid. The only player I see as being particularly good in the midfield for Real Betis is Isco, who can play well and pass the ball to forward players while also handling some Real Madrid players in the middle. As far as the Real Madrid defence is concerned, nothing Real Betis can do will stop Rudiger from playing well and keeping everything safe.
