The defender is 10cm taller than his opponent meaning he should have the beating of him in the air.
The duo have already faced off before in the Bundesliga and with Matip not being the most orthodox in possession, he can't afford to play around with the ball at the back.
Mohamed Salah vs David Alaba
This could be an area where the game is won or lost for Bayern Munich.
We've seen many defenders fall victim to the Egyptian's lightening pace and tricky dribbling in recent years and Alaba will have to be at the top of his game to keep Salah quiet.

The Austrian was branded as the best left-back in world football under Pep Guardiola but he appears to have lost some of his credibility in recent years.
He has to resist the temptation of getting forward as much as possible, because Salah will be waiting to pounce on any space that could see him bare down on goal.
If Alaba does go forward, the winger will have to do his defensive duties and help out his right-back whenever needed.

Roberto Firmino vs Mats Hummels
Marking Firmino can prove a real nuisance.
Not only does he pose an obvious threat in front of goal but his selfless movement can pull defences out of joint for Salah and Sadio Mane to profit.
Hummels will have to be wary of that, making sure his partner Niklas Sule is on the cover.
The German is a top defender with plenty of experience and he has previously come up against Firmino in his Borussia Dortmund days in the 2015/16 Europa League and against Hoffenheim in the Bundesliga.
Admittedly, the Brazilian has matured a lot since then, taking his game to the next level and his class could be essential in helping Liverpool decide this tie.
Firmino was exceptional during last year's road to the final in Kiev and seems to thrive under the lights on European nights.
