We have seen PSG win in the last four matches against Lens. PSG's past record against Lens is very good. Although it is Lens' home match, I cannot consider Lens as a favorite. However, in the last three matches we have seen good performance from Lens players. Lens won against Reims and Montpellier and drew with Auxxere.
I don't think it will be very difficult for PSG to win today's match. However, Lens' defense is quite strong. If PSG's attack does not play well, PSG team will not be able to secure 3 points from this match. I think Lens players will want to share points in this match. So PSG players will have to play very carefully from the beginning of the match and attack a lot.
Lens are like every other small teams that meet bigger clubs and have the desire to rise to the top but might not be able to so they settle for frustrating the bigger teams if not on a normal day, I think PSG would have them for dinner but since this is their coupe de France competition, virtually every teams participating would try to give it their best shot and Lens really gave it their all only they couldn't move to the next round because they were defeated on penalties by PSG.
