I'm not one of those overtly critical of Valverde but I think he's living on borrowed time now. His decision making, subs, tactics and lineups are really just off way too often. His love for Sergi Roberto makes absolutely no sense and at a time when Arthur is playing great, to drop him in a tough away game and to bring in Roberto in MF makes no sense. The refusal to drop Suarez, irrespective of how badly he plays is another shocker.
Suarez is a liability that can only be tolerated in home games but in away game and when Messi isn't present, his presence is toxic. The man can't control a ball, can't shoot, can't pass and doesn't have Messi giving him 3-4 one on ones and a tap in or two a match to paper over the cracks.
Griezmann is being criminally wasted thanks to Suarez.
