Bayern v PSG - Key Champions League battles

Bayern Munich takes on Paris Saint-Germain in the Champions League last 16, a heavyweight clash between clubs who faced off in the 2020 final.

After a strong start domestically, PSG's form has dropped off considerably since the turn of the year and coach Galtier finds himself entering a critical stretch of the season without Kylian Mbappe.

The France star, the joint-leading scorer in this season's Champions League with seven goals, will miss the first leg with a thigh injury and there are concerns over Lionel Messi too after the Argentine hurt his hamstring during Wednesday's 2-1 loss to Marseille in the French Cup.

With Neymar yet to rediscover his best form since the World Cup either, Galtier must devise a plan that will allow a diminished PSG -- whose squad was also hit by a stomach bug at the weekend -- to avoid another European disappointment.

Bayern appeared to have turned the corner after going through what their coach Nagelsmann called a "results crisis" following three straight draws last month.

The 35-year-old Nagelsmann has also been hindered by injuries to key players but the club brought in cover in January and expectations remain as high as ever in Bavaria.

The Italy goalkeeper made a costly error as PSG were dumped out by Real Madrid in the last 16 a year ago but is now entrenched as their first-choice goalkeeper.

PSG twice reached at least the semi-finals with Keylor Navas in goal before the arrival of Donnarumma, whose signing was intended to help the French champions win Europe's biggest club prize.

Bayern have signed Switzerland goalkeeper Yann Sommer as a replacement for Manuel Neuer, who will miss the rest of the season after breaking his leg while skiing in December.
