The 35-year-old World Cup winner was banned by the club after an unauthorised trip to Saudi Arabia.
"Yes, Leo is going to start tomorrow," Galtier told an eve of match press conference. "Obviously I've spoken to him, he's very relaxed, really keen to play, and very determined to claim another French league title."
With PSG out of the Champions League and only four Ligue 1 matches remaining as they target a record 11th title, this is likely to be Messi's penultimate appearance at the Parc des Princes.
After an uninspiring two years in France, the seven-time Ballon d'Or winner is reported to be lining up a blockbuster deal to play in Saudi Arabia next season where he would join his old sparring partner Cristiano Ronaldo.
His move to Saudi or even his departure at the end of his contract in June, however, have yet to be confirmed by the club or his agent father Jorge. But all the signs are that he is on his way out.
"Messi is a done deal. He will play in Saudi Arabia next season," a source close the negotiations speaking on condition of anonymity told AFP this week.
Galtier said he did not want to go into the six-day suspension which forced Messi to miss last weekend's 3-1 win over Troyes that left PSG six points clear of Lens.
Messi's opener was cancelled out by a Kevin Gameiro equaliser, but the result gave PSG an unassailable four-point lead over second-placed Lens with one match of the season remaining.
The Argentinian netted two finishes, including a superb bicycle kick, after goals from Neymar, Achraf Hakimi and Marquinhos got the champions off to a dominant start at Stade Gabriel-Montpied.
This is what actually happened, after one of the people who obtained the precious treasure, the used tissue, after the conference placed an advertisement on one of the popular sites announcing the offer to sell the tissue paper that Messi used for one million dollars.
Di Maria said, "Messi's situation is not ideal now, it is not easy for him to stay in a hotel with his family, people are used to respecting the privacy of players, but with Leo we can no longer move much, there are always cars and motorcycles nearby to protect the team."
