Mbappe trained on the eve of Tuesday's heavyweight contest, a repeat of the 2020 final, which Bayern won 1-0.

"We're not sure yet whether he will be on the match sheet," said PSG boss Christophe Galtier on Monday.

Galtier added: "Kylian did the whole session today. We made the decision that he would train with everyone today.

"We will decide tomorrow [whether he plays] after discussing with him and the medical staff.

"If he is on the match sheet, he will play."

Lionel Messi, who has received treatment for a hamstring problem, has also been named in the PSG squad.

'Bayern are not favourites'

If Mbappe and Messi do return, it would be a huge boost for Paris St-Germain, who have lost their past two domestic matches.

The Ligue 1 leaders have never won the Champions League and PSG know they must raise their game to get past Bayern, the six-time European champions.

"We're prepared for that clash. We have the team to play a great game tomorrow," said Brazil forward Neymar.

"I like to play these big games against big teams. We have this ability [to switch to Champions League mode]."

Galtier added: "I don't think Bayern are the favourites. It's 50-50. No one will be qualified after tomorrow's game.

"Bayern have been better lately and for some reasons it's not the case for us, but I have a bigger squad at my disposal for tomorrow."

Is Bayern's dominance bad for the Bundesliga?

'A big game of football'

In contrast to PSG's recent form, Bayern are unbeaten in all competitions since 17 September.

Forward Thomas Muller is relishing two games against PSG, with the return leg in Germany on 8 March.

"Two very good teams with very good players," said Muller, a two-time Champions League winner, when asked about the tie.

"Sadly one cannot go through to the next round. A big game of football."
