It's very funny to see PSG who are very ambitious about wanting to win the UCL title for the last few years but they continue to fail every year. Everything has been done, including installing a deadly trio on the front line containing classy players such as Messi, Neymar and Mbappe, but their presence cannot bring PSG to the main podium to celebrate their success.
Mbappe has seen his condition at PSG realistically, he only earns money there but has very little chance of winning the UCL trophy. Moving from PSG was the final solution for him who still really wanted to experience the pleasure of touching this prestigious trophy. He is still young, his career still has a long way to go, moving to another club would not only open up the opportunity to win the UCL trophy but could also give him the chance to win the Ballon D'or.
PSG are doing well in the French Ligue 1 race, even though it's not as balanced as it ought to. They're a team expected to perform better than they're doing now judging from the performances of previous seasons. They're just a few points ahead and it's very much not buoyant for them as the increase in the league's intensity may unintentionally lead to their drop in position which they as a team shouldn't let to happen.
They've also been able to advance to the round of 16 of the UCL and their Spanish opponent, who's not really a tough side as them but maybe stands a chance to advancing to the next stage. They'll have to be extra prepared for the game ahead. They also have to be careful about their league race. They've got to stay in shape and capacity too. They've got to use the games during the early second half of the season to cover up their tracks and also strive to be far better than Sociedad and even advance to the quarter finals.
