Real Madrid have made a lot of efforts to strengthen their XI this season. However, they still need to have stronger players in the midfield, they have not been able to strengthen it that much down the line. Barcelona's XI is currently very strong and they are fighting with more excitement than last season. According to Barcelona's performance, I think they are ready to compete a lot this season, if they can play strongly against Real Madrid this season, they will be in the lead to win the championship this season as well as last season. However, if Barcelona will have enough competition and excitement with Real Madrid this season, it will be impossible to confirm now, although Real Madrid is planning to strengthen their players in the meantime.
Replacing players like Tony Kross or Modric will be very difficult. They are really making a lot of effort to try to make Real Madrid a team that can compete with Barcelona, but they are really struggling, we need to be patient.It takes time and perseverance but I'm confident they'll get there.
