Really intrigued to see how Bilbao approach this match.
In the game (way) earlier this season at the Camp Nou, they played relaxed and that allowed Barca time to find the gaps. Unfortunately, Munir played in that game, and he was unable to capitalize on a few good chances in the first half. Second half was really much of the same IIRC, Bilbao didnt really offer much and Barca continued to find gaps and eventually Neymar was able to put away two.
In contrast, at the San Mames, Bilbao pressed like crazy, and up until the first goal (which took a wicked deflection), the pressure seemed to bother Barca. Nonetheless, eventually Barca figured it out, and playing that high line as Bilbao did, proved to be their downfall.
Looking ahead to the CDR Final, Barca is going to run amok on them if they are one-dimensional. I don't think its realistic for them to attempt to press for the first 45, nor should they strictly play on the counter. They definitely have quality, and if they find a good balance between pressing & absorbing pressure, then they could really give Barca a fight.
