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.
at least they now care about the current line of defense.
Over the last few seasons it seems that Bayern's philosophy is still sticking to the best defense is to attack.
But with Lewandowski missing now it makes them realize that their goal productivity will be a bit less and indirectly they have to improve their defense and De Ligt is very good I think.
With them at least nothing will be the same during the few games this season where they only focus on attack and forget about defence.
