Negative #3: Anonymous Odegaard

Improving on the ball demands having enough of it in Paris to get Odegaard more involved. If Arsenal can make it happen, the playmaker with the armband will have to do a lot better.
Odegaard never asserted himself in this game. Never showed the quick feet and keen eye for a pass that unlocks so many defensive structures.
Without ingenuity from Odegaard, Arsenal were reduced to simply playing for set-pieces and hoping for some individual magic from Saka. If that sounds familiar, it should. It's the formula Arsenal still travel with far too often.
The blueprint stays the same because Odegaard is an isolated figure between the midfield and forward lines. An assist-maker forced to create on an island.
Odegaard needs help, but it's tricky predicting where it will come from. Unless Arteta goes bold for the return fixture and moves Ethan Nwaneri into the middle to support his gifted but lonely string-puller.
Luckily, the Gunners only need a couple of creative moments to turn this one around.
Positive #2: It's only 1-0

PSG showed off their attacking prowess early when enterprising wing wizard Khvicha Kvaratskhelia teed up Dembele. More goals should have followed, but the away side squandered too many chances.
None might be as costly as substitute Bradley Barcola prodding the ball wide of the far post with barely five minutes of normal time remaining. Dembele's replacement had gotten behind the Arsenal back four all too easily after a quick and smart one-two, but the finishing touch was lacking.
Barcola's miss preceded another sub, Goncalo Ramos, hammering the ball off the bar. Just like earlier, Ramos had the freedom of the box to pick his spot, but he couldn't make the space count.
These missed chances represented huge swings of good fortune for Arsenal. Arteta's team was out-thought and thoroughly outplayed, but the group that travels to France will know one set-piece or one early bit of brilliance from Saka will push PSG nerves toward breaking point.
