Barca boss sticks to his guns on how to defend

After keeping clean sheets in their first seven matches in all competitions, Barca’s back line was beaten twice in the first 26 minutes of Tuesday’s Champions League game at Paris Saint-Germain.
And both goals came from set-pieces — a familiar failing for the blaugrana side over recent seasons, as bigger, stronger opponents have apparently scored at will from corners or dead-balls around the box.
