If it's in their domestic league competitions, I don't thnk they'll be missed but they'll definitely be missed in the Champions League, those players played a major role in PSG having their best Champions League season and it's quite unfortunate that they won't be available to do similar thing in the beginning of this season Champions League tournament but as for Lens, PSG would scale through.
It is a fact that things are now very focused on seeing how far the defending Champion will go in the UCL, they only expect the best from PSG, of course we have to realize that the Teams that have entered this UCL are of a high level, they should all be treated with the same care Because only the best are those who enter this competition, so it is careful.
PSG will find it hard to get the job done this season and I believe they'll try their best after all, they have the best players who are very good at getting the ball in the back of the net and the manager Enrique has turned the players to something different from how they were when he first joined the club. When it comes to the champions league I see the challenge as a strong one for PSG, we know all teams will be getting ready to defeat them at least to prove a point but when it comes to the Ligue 1, I feel PSG don't have much problem since they are too familiar with the clubs in the league and they are ready to get more points from the smaller teams than the big clubs, this is the only way they can stay fit but going head to head with the big clubs they perfer to get a draw and it keeps them ready for the champions league like they did last season where they have already won the league before facing the champions league games.
