A bit late to this but I don't agree that Jenkinson is all that much worse than Sagna. For one, he's a much better crosser of the ball. He'll improve.
Biggest problem this match was just a very slack attitude, I think, especially going forward. If we manage to score a goal, that relieves a lot of the pressure the defense is under. Same if Arteta doesn't get sent off.
That's a bit harsh. We could push all but Bayern; Real Madrid and Barcelona are particularly vulnerable to an upset, I think. Frustrating result for sure, but to win the CL (and I'm not saying that we do have the quality to win the CL, because I don't think we do) you have to beat the best somewhere along the line. At least if we go out, it'll be to a quality side.
Jenkinson is careless with the ball, defensively suspect, and going forward can be good can be crap. Overall very average imo.
Our attitude today sucked. Defensively we were reasonably solid until the send off, which wasn't a send off, then it went south. Offensively we weren't interested today. Didn't really look like it. Such a crap display.
We can only draw PSG, Bayern, Barcelona, Atletico or Real Madrid. Against Atletico we would struggle, we would give it a good go, but ultimately we would find that really tough going. PSG are the easiest of those teams. We still lack the quality to challenge Barca, Bayern, Madrid so drawing them will see us go out no matter what.
Today's performance is the reason why we don't win things. That was a Blackburn/Bradford like performance where we just expected to get what we wanted. Unless we actually turn up to play every game we will continue to have situations like today. Napoli are a talented team, always was going to be hard, but they didn't look that good today we were just dreadful.
