Because Chelsea has been abandoned by 2 defenders, they are very interesting to bring Matthijs de Ligt to Stamford bridge, it's very possible soon if they have opened the negotiation., but Matthijs de Ligt is more interested to play with Bayern because the bavarian is more likely to win the title, such as Bundesliga or Champions League than Chelsea. So if Juventus lower the price to 50 M Euro, that possible Matthijs de Ligt will be landing in Bayern in the near future, if not yet deal, maybe Bayern can add a clausula package with Lewandowski. who knows.
Between Bayern Munich and Chelsea have the same position because they have loss defender player, Bayern Munich leave by Niklas Süle after not extended contract and move to Dortmund next season, bad side with Chelsea have losing two defender on this time after leaving by Antonio Rüdiger move to Real Madrid with free transfer and Andreas Christensen to Barcelona. I think Chelsea most serious with Matthijs de Ligt because they have loss two defender than Bayern Munich still have many option with other player. Actually depending how serious offer give by Chelsea and Bayern Munich for Juventus, which one brave give expensive values transfer.
