Arsenal, Atleti, Bayern and PSG: Where the Champions League semifinals could be won or lost

If Lookman isn't able to find his confidence, Atleti coach Diego Simeone might want to leverage Alexander Sorloth instead. The 6'5" Norwegian striker is a battering ram of a player and might be just what Atleti needs to throw Arsenal off its course.

Bayern Munich vs. Paris Saint-Germain (4-5 on aggregate)

At the end of PSG's breathless nine-goal thriller with Bayern Munich last week, coach Luis Enrique struggled to put the game into words. 

"I have never seen a match with this kind of intensity," Enrique said. "This is not the time to point out flaws; we just need to congratulate everyone. We deserved to win, we deserved to draw and we deserved to lose today. It was a fantastic match. It has been, without a doubt, the best match I have ever been involved in as a coach."

It's difficult to pull predictions or analyses from a game as wild as that one; these teams aren't likely to play out another 'greatest match in history' when they face off in the second leg in Munich. But there is one fascinating statistic from the first leg that's worth calling out: PSG scored five goals from five shots on target, while Bayern forced several big saves out of PSG goalkeeper Matvei Safonov on its way to scoring four.

There's plenty of nuance to this (a lot of PSG's chances were low-likelihood shots executed brilliantly by their takers), but in broad strokes, what this stat tells us is simple: Bayern keeper Manuel Neuer was just okay in the first leg, while Safonov, despite conceding four goals, made several important saves that wound up winning his team the match.

Both PSG and Bayern feature impossibly talented attacking lineups and best-in-class defenses. It's next to impossible to separate them, both on paper and in practice. And that means that Neuer and Safonov, despite looking like the least important men on the field in a nine-goal thriller, might just wind up being the most important ones of all. If Neuer can excel at home, he'll help Bayern overturn its one-goal deficit; if Safonov can excel as he did in the first leg, he'll seal this tie for PSG instead.
