It seems he's Penaldo/Madrid fan...
Let's see. It's not nearly as bad as that other chump. However, he probably shouldn't have been making fun of Messi like that.
Messi has done nothing (as in being invisible)
Is he even playing?
Its something along these lines, right?
He showed great promise at Roma then went on to continue playing well at PSG. Whenever he's gotten a run of games at PSG he's done great, many fans were angry when he got benched after Thiago Silva got healthy and Luiz started over him. Laporte gets consistent football when he's healthy and he's consistently inconsistent with some very, very bad performances.
Gerard Romero pretty much said that theirs a lot of CR7 fans in La Masia and weren't punished so in this case Guillemenot is safe unless he decides to pull a Sergi Guardiola and shit on Catalonia.
Anyone who thinks Ronaldo is best is stupid. It's that simple.
You said "fail safe", not "stop gap". You shouldn't confuse the two.
And speculation about why a player was signed says nothing about the role that that player actually fulfilled during his time at a club.
LCB and RCB scarcely qualify as multiple positions, and many CBs can play both. Marquinhos has proven a great many things, not the least of which being that he could change clubs and continents as a teenager, and secure a starting place in a club the size of Roma, in a position that usually requires much more experience to master.
