Pochettino doesn't really care about Sergio Ramos being a regular player so he is mostly on the bench why so look at the other defenders who are still solid at their best, so Pochettino prefers another defender over Ramos to start.
Messi is still only able to process the ball to continue to supply to Mbappe and his finishing is good enough for Mbappe for Messi is still a little unlucky in terms of scoring goals.
Otherwise just one goal with 1/2 season in league 1.
Well in the Champions League he has scored a couple of goals so far. In Ligue 1 it's definitely not going well for him. If I were Pochettino I would also leave Ramons on the bench. He doesn't seem to be at top level anymore. Way too bus with things that happen outside the pitch. Crazy that PSG decided to pay him such a high salary although they knew that Ramos is frequently injured and misses most of the games these days.
There is no doubt he was very good player and have very good career as professional footballer specially he was very good at Real Madrid and now here at PSG because of his quality but sadly recently he is facing some serious injuries just because of this not able to play PSG is paying him because he is in contract with them for this all as this contract is going to end surely they are going to leave him which is very simple, but one thing is sure they have to pay him until this contact is going to end even its very high fees.
But, the good thing with PSG and Pochettino is that they have some good and reliable substitutes, so they are using them for their good game.
