PSG might have lost three of their 23 league matches this season, but the capital giants have again proved to be far too strong for the rest of the division overall, boasting a 12-point advantage at the summit.
Les Parisiens will win a ninth Ligue 1 title this season unless something quite extraordinary happens, but it would be fair to say that all is not well in the camp.
Indeed, head coach Tuchel and star forward Kylian Mbappe exchanged words when the latter was replaced against Montpellier last weekend, while Neymar's commitment to the cause has again been questioned after he missed Tuesday's league clash with Nantes.
A rib injury was allegedly the reason for Neymar's midweek absence, although the Brazil international had celebrated his birthday with a lavish party last weekend.
On the field, things are looking good for PSG as they have won their last seven in all competitions and have not lost since the start of November. There remain question marks surrounding the French champions, though, and they will have more than one eye on their upcoming Champions League clash with Borussia Dortmund.
Lyon, meanwhile, finished third in Ligue 1 last season but have struggled for consistency this term, with a total of 33 points from 23 matches leaving them in sixth position in the table.
Les Gones are seven points off Rennes in third, while they sit 13 points off second-placed Marseille and 25 from PSG, which is quite staggering with a lot of football left to play this season.
Rudi Garcia's team have not actually won in the league since beating Toulouse on January 26, losing at Nice last weekend before drawing 0-0 with Amiens on Wednesday night.
This is not exactly the match that Lyon would have earmarked to return to winning ways, but they are still capable of picking up a positive result despite their struggles this season.
Indeed, Lyon have won two of the last four Ligue 1 meetings between the two sides, although they have not overcome PSG in a league match at the Parc des Princes since October 2007.
PSG Ligue 1 form: WDWWWW

Lyon Ligue 1 form: LDWWLD
Lyon form (all competitions): WWWWLD
Mbappe and Mauro Icardi are both expected to continue in the final third, though, meaning that Edinson Cavani - strongly linked with a January exit - is likely to have to accept a spot on the bench once again.
PSG possible starting lineup:
Navas; Meunier, Kehrer, Marquinhos, Kurzawa; Draxler, Gueye, Verratti, Di Maria; Mbappe, Icardi
Lyon possible starting lineup:
Lopes; Rafael, Marcelo, Denayer, Marcal; Tousart, Mendes; Ekambi, Aouar, Terrier; Dembele
We say: Paris Saint-Germain 2-0 Lyon
Lyon will be in better shape in terms of players than they were against Amiens during the week, but it is a tough ask to expect Garcia's side to pick up a result in Paris considering their form this season. We fancy the runaway leaders to put another three points on the board in relatively routine fashion.
