I'm not a Barca fan (I always loved their teams though) and rarely watch them in La Liga so I'm not an expert on your players, but I'm not accepting that you have only 3 technically good players. Off the top of my head, Pique, Rakitic, Alba, Coutinho and Suarez are all technical players. They are certainly technically better than Henderson, Milner, Origi, Wijnaldum and Shaqiri. The difference is that Liverpool's players are well drilled in the way they play and would run through brick walls for Klopp. That willingness to work hard off the ball is something Pep's great sides had and it's so important at the top level. It's something Barcelona need to find again to be successful in Europe again. I would say a new manager is needed, but also new players - young, talented ones who want to work hard and win things.
