Madrid fans are kinda thick.
They are envious of Barca, which I understand as I would be too if the Mancs were getting trebles and winning the CL 3 times in 7 years, but they need to understand that sacking managers because of three losses isn't going to make them compete with Barca.
They need to know that their club is run wrong from the off, this squad is as inbalanced as it gets and even Carlo lost 4-0 to Atletico last year (in fact, he never beat them in a league match), lost to Barca in the Camp Nou, barely went through to the QF in the CL last year (lost 4-3 at home to Schalke). In the months of January and February, the team lost so many points, they allowed Barca to win the league again, after having a nice gap going into the Christmas break.
Did they fix their squad issues? No, Perez decides not to extended Hernandez's loan despite playing excellently, gets rid of Coentrao, leaving only Marcelo as the recognized LB in defense, buys a useless RB in Danilo despite having Carvajal and Arbeloa in there, they recall Casmiero and buy Kovacic (two good moves in the long term) but he believes starting Modric and Kroos is better and they still haven't properly replaced either Ozil or Di Maria despite the latter wanting to return so badly for them after a failed stint with Old Trafford.
The Madrid fans need to know that cheering for Galacticos over actual trophies is what led them in this rut in the first place. They need a good DOF who is not connected to Perez who puts the club's needs first instead of buying unneeded big names. Their academy produce good players, they never end up giving them any chance because they are too concerned with playing the big stars (case in point Morata who was sold to Juve and ended up scoring against Real in the CL and eliminating them, now Madrid wants him back, but he doesn't care). The fact that they are directing their anger towards Rafa instead of Perez (and let's be honest Rafa hasn't been terrific either but it is too early to tell) tells you that they can't see the wood for the trees.
