The French champions advanced from the last 16 with a 4-1 away win in the first leg against Barcelona before suffering in the return leg at home in a 1-1 draw.

In Ligue 1, their best performance of the season came last month in a 4-2 win at Olympique Lyonnais, which was followed nine days ago by a 1-0 home loss to Lille.

"I agree that we've been better away from home," Pochettino told a news conference on Monday.

"It is something we will have to look into at the end of the season but let's hope things start turning around tomorrow."

PSG suffered in Munich last Wednesday with the German champions boasting 31 attempts on goal, but Pochettino's team were ruthless up front with Kylian Mbappe scoring a double.

They will, however, be without captain Marquinhos after the centre back picked up an adductor muscle injury in the first leg.

Pochettino said Marquinhos was not included in the squad for the game at the Parc des Princes on Tuesday.

Italy midfielder Marco Verratti is eligible following a week-long isolation after being infected by COVID-19 while on international duty, but he is also unlikely to start.

Italy full back Florenzi also tested positive for COVID-19 upon his return from international duty.

Pochettino, who labelled Bayern as the "best team in Europe, best team in the world," said PSG's attitude would be key.

"It was already hard to keep the ball against Barcelona already, it doesn't matter who is playing. It's a question of collective attitude," he explained.

Meanwhile, Bayern coach Hansi Flick has urged his players to be more clinical and force PSG into mistakes as they look to overturn the 3-2 deficit.

Bayern missed a bagful of chances in the absence of top scorer Robert Lewandowski, falling to their first loss in the Champions League in more than two years.

Flick, however, is confident his side will respond positively.

"We had many chances but we were not as decisive as we should have been and we have to improve," Flick told a news conference on Monday.

"We have to make sure tomorrow we show same ambition that PSG showed against us. We have to force them into making mistakes.

"We know we have to score at least two goals.

"It will be a tough task, but these are the games we play football for. We want to cause a mini upset in Paris."

Bayern will have their work cut out trying to neutralise the threat of young PSG forward Mbappe, who has scored 33 goals in 39 games this season.

"Mbappe will be the world's best in the future, he's fast, technical and scores important goals," Flick added.

"Considering his age he's so well developed."

Flick said Lewandowski, who trained for the first time since sustaining a knee injury last month, would not make the trip to Paris, but Leon Goretzka, Lucas Hernandez, Jerome Boateng and Kingsley Coman are available for the game.
