Just as fairly reliable goal scorer in the Domestic League, that all I think Messi contribution while being part of PSG, don't talk about other competitions in Europe like the UCL because Messi performance with PSG in the UCL is quite bad and has nothing to do with feelings that are too deep because he left Barcelona because professional player after leaving then he will focus and try to play as well as possible for the team he is now defending.
By the way yesterday PSG managed to win the match against St-Etienne which is lower team that is currently in the relegation zone, this 2 - 1 victory made Dembele the center of attention because he created 2 goal for PSG victory and so far Dembele has been the most prominent player in every match played by PSG, he is like substitute for Mbappe.
Dembele is currently very extraordinary, his performance looks increasingly better now because from the last 5 matches he has created 6 goals and that is very fantastic for his current development and Dembele has currently collected 10 goals in the Domestic league and of course that is a compliment to him and hopefully Dembele does not fall easily in the game so as not to get injured again because currently PSG fans have high hopes for him but when compared to Mbappe it is clearly not balanced because what Mbappe did with PSG was extraordinary but I have not seen that Dembele is really the figure wanted to replace Mbappe.
Dembele is good but overall he is not as impressive as Mbappe and is still far from what is compared because Mbappe's performance at PSG is extraordinary, and Dembele has not done half of what Mbappe did at PSG and I hope Dembele can be sharper in all aspects, both skills and goal-scoring instincts and if he can do that then next season there might be a comparison between him and Mbappe.
