We know the greatness of Mane when he was at Liverpool and this clearly will give high expectations especially in terms of Mane's performance can still be good there.
Even though it is still very difficult for the top scorer when there is Lewandowski in the Bundesliga, Mane's name will still be lifted with some achievements in the Bundesliga next season, I think it can still be done for Mane.
Yes, you are right, for me Mane has a lot to offer and give, I hope that this season he makes one of the plays to which he has us accustomed, however it is as you say Lewa is one of the best, and for me he is the owner of the ballon d'or and not Messi at the time they were competing, so here it is a question of merit.
Now Lewandowski is about to leave Bayern and of course this makes Mane's chance of making a surprise in attack even bigger because after Lewandowski's death now he will indirectly become the ideal targetman for Bayern.
Obviously this is a huge advantage for Mane and I wish him all the best in his first season in the Bundesliga.
