Chelsea could overtake Barcelona if they wanted, because one of their obstacles in signing Lewandowski apart from Bayern Munich was holding back the striker a bit as well because Barcelona could not offer a higher price to Bayern Munich. Of course the opportunity is wide open for Chelsea to talk Lewandowski in order to join them. But so far there has been no serious statement from Chelsea.
Chelsea should have realized this from the start, when Barcelona was unable to make an offer that would ensure Bayern Munich let go of Lewandowski, but at this time Bayern Munich did not feel 100% willing to let go of this quality player. Maybe with the finances Chelsea have they should be able to increase the price which can give Bayern Munich a second thought.
Maybe for today it will be a little different, because Barcelona are now almost certain to make a deal with Manchester United regarding the transfer of De Jong and it is certain that they will get enough fresh funds to bring Lewandowski.
Although there are some things that may be unavoidable regarding their finances, but I still feel that the proceeds from the sale of De Jong will definitely be used for Lewandowski if they still want to pursue.
Even though Chelsea have better finances, signing Lewandowski is not easy, because Lewandowski himself only wants to play for Barcelona and even Lewandowski has rejected offers from other clubs. Therefore, if Barcelona cannot sign Lewandowski then it is certain that Lewandowski will stay at Bayern Munich and will be free next season. After all, there is another player who is currently being linked with Chelsea, he is Neymar and I think it is something great if Neymar is finally part of Chelsea next season.
