Hello All, been a lurking to Barcaforum a long time and Barca fan over a decade, and decided to post.
I think Arturo Vidal is an excellent signing and I agree with the sentiment he add a competitive/firey edge sorely needed. In truth he probably should have been red carded (two yellows) the Barca Juve CL final years ago (3-4 yellow card worthy fouls with only one called)--however he is smart and might have played differently if he got a deserved early yellow. I have watched him a lot Chile, Juve and Bayern.
He is totally necc with the departure of Paulinho. He is a lot like him physically, but is a more skilled player, much better touches and vision, and much more versatile footballer. He can seem borderline reckless, but there is usually a purpose to it. I think he also is more of a leader and with that competitive/firey edge.
As for the poster would said it is a departure from Barca ideals and think they should strive to get back to just killing opponents when 2 levels better pure football--like the one to produce probably the three of 5 best club football teams/seasons, I think a reality check is in order. Those teams had generational players like Messi, Xavi and Iniesta as the core. That is what made that possible (and other world class players like Puyol, Pique, Busquets, Etoo, Alves and later Alba, Suarez, Neymar). That is unlikely to be duplicated and Real has been much better about winning CL games they shouldn't, beating more equal sides to them via gile and persavereness (and sometimes a little luck).
Preparing the team to beat you one way and only one way, and being so good to do it despite whatever tactics are designed to thwart it (with Messi, Ineista, Xavi countering anything in front of them), that is NOT a model I want to see Barca try to emulate. I think Barca needs to be much more pragmatic--there is only a few more years to capitalize of the last of these 3 generational talents--that all amazingly came from La Mesia and where probably no 3 players of this quality will ever again emerge from any clubs youth systems within a short span.
The bottom like is Barca had some incredible uninspired efforts in the CL the last 2 years--at Roma, at Juve, at PSG. (You can also go back to ties they shouldn't have a little bit further back such as vs Atletico). While I think cumulative season fatigue was part of it and coaches blame is part of it, it was also a remarkable complete implosion, lack of fighting spirit, and lack of leadership to let those games get out of hand. I think a player like Vidal reduces that risk of a team having a complete loss of edge. Even though he may not be what he once was and coming off a knee injury--this is a wise short term acquisition that may prove very important in a handful of really big moments--he not need to be used heavily.
