Lewandowski will surely be missed at Bayern Munich for his contributions and even though Mane will not be the perfect replace for Lewandowski,he will surely bring more fire power to the Bayern attack next season.
Lewandoski would have been missed if the situation had been that the club was not almost close to getting a most suitable replacement for their champions League campaign. Ronaldo may most likely be confirmed at the club in the coming days, and if so...he can certainly assure the team as many goals as lewandoski could have provided in the coming season, For Mane, it will be great for his career to play alongside in attack a formidable player as Ronaldo who still has much to give.
