Lionel Messi is poised for his first appearance of the year as Pochettino's team tackle Reims on Sunday, with Kylian Mbappe also set to feature after recovering from an adductor problem.

Messi made his PSG debut as a substitute when PSG and Reims met in August, with a double from Mbappe earning a 2-0 away win amid a whirlwind of global interest in the game.

"It will definitely be a different match to the first one we played against them," Pochettino said.

Messi is fit after a brush with COVID-19, and Pochettino added: "Leo Messi has trained this week. We are pleased with how he is coming along. He is going to be in the squad tomorrow.

"It is always good news when players who have been out for a while are able to return and be back in the squad to help the team."

Mbappe scored in last weekend's 2-0 win against Brest, before a midweek medical bulletin pointed to an injury.

"We are happy to see the way that his problem has evolved," Pochettino said. "He trained with us in the last two sessions. He is going to be in the squad tomorrow. We will decide tomorrow if he starts or is on the bench."

Messi has not scored in his last five domestic matches for PSG and has just six goals across all competitions since arriving from Barcelona.

He has hit the woodwork more than anybody in the French top flight this season (six) – more times than the entire Reims squad (five).

PSG have won each of their last three meetings with Reims in Ligue 1 without conceding a goal, achieving as many clean sheets in this sequence as in the first 11 between the two clubs in the 21st century.

Reims will clearly do well to take anything from Sunday's game, having not scored in their last two Ligue 1 games and with PSG having won 12 and drawn one of their last 13 home games in the competition.
