Mathieu will come for sure. The other one, no one knows. Would be amazing if its Hummels or Benatia, but perhaps thats a tad unrealistic. Its time for the scouting team to do some work and the management to listen and consider. There are plenty of gems out there in the big world of football, but you need to have an eye for talent to see that.
Last year we had the chance to sign Benatia for cheap, but the club and those responsible could not see further than a certain brazilian CB who plays for Paris-Saint German, the team that certainly dont need money. Had we taken a chance then, it could have been much different.
