PSG successfully defeated Monaco 4-2 in their last meeting and this is a club that occupies the 3rd spot so I feel the game to Lens will be an easy one except PSG would want to relax and lose the game since they are already passing their competition with about 10 points.
The fact that Paris Saint Germaine thrashed third placed Monaco in their last French league game doesn't necessarily mean that they'll have an easy game against Lens later tonight if you ask me. In many occasions this season, Paris Saint Germaine have either lost or dropped points in games they were favorites to win and playing away at Lens who we all know can pull up surprises on their day might still end in a disappointing result for the French champions.
Instead of staking on a Paris Saint Germaine straight win in that game, I'll rather stake on 2+ goals to be scored in the game.
