PSG are in very good form that's for sure. However, it is not certain whether they will win. However, I consider PSG as the favorite in this match and decided to bet on PSG.
Lens is strong at home. I don't remember the last time Lens lost at home. The team has been able to maintain the winning streak in the last four home matches. This is why it is not going to be easy for PSG to win this match. It will be difficult for PSG to win, but Luis Enrique will definitely want to win this match. If Mbappe can play well in this match then I believe PSG will win.
The match with Lens will be only mid-January, so it is a little early to make such a long-term forecast. First, PSG will have to play a match with Toulouse for the Super Cup, and another cup match (perhaps this will not be a difficult match for Enrique). Lens last lost at home in September, but you are right, they really lose home matches very rarely, although it will not be easy to do this against PSG.
