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.
The presence of De Ligt in the ranks of the Bayern Munich squad makes the defense of the defending Bundesliga champions even stronger. During his time with Juventus, De Ligt transformed into one of the best defenders in the world, I think it's only natural that Bayern Munich redeemed De Ligt at a fantastic price.
Bayern Munich are very lucky to win the battle with Chelsea who are also eager to sign De Ligt. De Ligt seems to have his own reasons why he finally chose to play in the Bundesliga rather than appear in the Premier League competition.
