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.
