This one could go to pens, but I'm not sure that will be on Pep's mind when picking the lineup.
Last time out against Arsenal he went for shock value. We had Navas at full back for the first time and basically blitzed them for the first twenty minutes before they found their groove. Not taking our chances was, as is the story of our season, the reason we ultimately came away with only a draw.
Hard to predict how he'll set things up this time, but I don't see us going through the entire game without GJ making an appearance. Hell, maybe he'll even start, just for more of that shock value.
