We are no more a possession team. We are so often around 50-60% this season and relying on players' individual brilliance to create chances. One game against Levante changes nothing. We need somebody fresh and explosive to add another dimension to our attacking play. I hope Dembele can do that.
BTW Playing tiki-taka to break bus is too hard. Even our prime-time 09-11 team isn't that effective. The failed experiments of Ibra, Alexis, Fabregas and Neymar (success only after Suarez's arrival). I believe there's a tendency to drop tiki-taka obsession (since Xaviniesta never ever again) in favor of fast transition play (Modric, KDB very typical). However, I believe Modric and KDB-type player will be confined if more and more teams learn from ATM. The next step may be using Messi (or Dembele?) type players to carry the ball forward.
AGAIN: I don't think we are a great team right now, despite our record. Ter Stegen and Alba are having a great season. Paulinho is a surprise to other teams and they don't know how to deal with it now (but they will figure it out soon). EV knows La Liga. I followed him when he coached a completely messed up Valencia. He just knows some tricks about how to get points (a bit like Sir Alex).
