While I agree Hansi flick could do better hopefully with what he performed in his first season..
 You could be surprised with club performance in every season though so don’t put too much high hope  until you see them in action.
While it looks like Realmadrid  having a bad time, everything could change when the season begins and you would be very surprised with whatever performance they pull up  , even with their current squad they still have a strong one, they just need proper management, getting more defenders could help a little but thats just not really the problem.. I think some of the problem lies in the mieldfield aswell and now, one of their mieldfield strengths ( Bellingham) is going to have a surgery which will make him out for a while so imo I think there’s more to the mieldfield than the defence
