With the signing of De Ligt and even though Bayern Munich lost Lewandowski. It feels like they are a stronger team now than they were 2 months ago. They needed better defensive players and they've now got De Ligt with a 5 year contract. In terms of attack, they've got Mane to run down the wings and create more chances.
Bayern Munich's defense and midfield are strong enough for next season. But with the loss of Lewandowski, I'd say Bayern Munich's attack will be a bit weaker. Sadio Mane cannot be considered as Lewandowski's replacement. In the last 3 seasons in the Bundesliga, Lewandowski played 94 matches and scored 110 goals. Sadio Mane doesn't seem to be able to score that many goals. So if Bayern Munich does not get a new striker, then they have to change their match strategy.
true, even though bayern get mane and de ligt in the squad but it will not be enough to compensate for the loss of bayern because of losing lewandowski (the former bayern goal machine). Kahn also realized that their current line of attack was very weak. I personally still have a question mark about why Bayern doesn't want Cristiano, because apart from Lewandowski, Cristiano is also a sharp striker and is also able to provide many goals for every club he plays for.
