Not particularly worried about Liverpool vs. Barça.
Redcafe tends of overrate Liverpool due to what they're doing this season in the EPL. As we've seen in the CL group stages, any team that plays a possession based team with any kind of quality is able to overcome Liverpool's high press. They would be considered fortunate to have qualified all things considered. Also, arguably La Liga as a whole is far more press resistant from top to bottom than the Premier League. Whereas teams panic vs. Liverpool domestically, European teams are more able to handle them and we'll see this vs. Barça.
Alba, Pique, Roberto, Busquets, Rakitic, Arthur, Coutinho, Messi and Suarez are more than able to deal with high pressure.
