Actually, I think Lucho pushes for older players (Mathieu, Nolito, Arda, Gameiro) as he wants instant impact while he is here (which won't be long).
Imo. Robert and Bartomeu (spoke about re-sale values himself) prefer younger players.
Mathieu was Zubi choice,he wanted him in 2013 and wanted to pay his buyout (10M at that time) but Neymar deal left us with zero money back then.In 2014 Lucho wanted one of Benatia and Marquinhos (20 & 27 of age at that time)
Gameiro is btw Roberto choice too,the guy himself spoke about he regret not getting him for Atletico and losing him to Sevilla.
I know that isn't gonna be a popular opinion,but I think the post Pep ear shows that there should be a balance between the Coach,Sporting director and the freedom the board gives them
With Tito(RIP) & Tata,the coaches were 2 guys that had a job that was too big for them.transfers was basically forced on them.Tito asked directly for a new CB and they gave him Song.next year Tata didn't even get a single signing.Rosell also seemed to give Zubi a little freedom with his work.very strict budget for example.
When Lucho came,a Barca legend and ex-captain.Bartou gave Zubi more freedom to work and Lucho had more say in the transfer.That was one of our best summers despite some shortcomings .
Zubi choose Mathieu,MATS,Vermaelen for example,Lucho got Bravo,Rakitic while Suarez was sort of mutual decision.Douglas was probably the board choice (or Zubi).
Next year there was no sporting director,instead a transfer committee that consisted of 2 business guys and 2 who are 70 years old guys. Lucho was given full authority and we end up with Arda and Vidal
This year we have a new sporting director and we have a coach who has a say in the transfers, I don't think it matters who wanted whom as long as they can reach a good final decision.which seem to be the case.
My point is,the coach is the one who at the end will use those player so he should have a big say in who comes.but at the end he has very little time to watch players around the world or even outside Liga.he has to be informed by the players that could suit his style.At the end a mutual decision should be made.Right now I think we have that mix and I hope it will work probably.
