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.
Robert Lewandowski is an excellent striker, but Bayern Munich is too strong to rely on a single player. Bayern has signed a couple of world-class players, which has already increased team support and strengthened the squad. Sadio Mane and Delight are very good players that every team would like to have in their squad, and Serge Gnabry's contract renewal is a huge boost for the team; I even see them winning the UEFA Champions League next season.
