I think that if Barcelona doesn't have any problems again with their finances, Lewandowski will exactly move to Barcelona. Because he only considers moving to Barcelona only. This means that the chance for Barcelona to add this great player is big enough. This should be a good combination of Lewandowski and Aubameyang in the future to strengthen the attacking lines.
The main barrier for the transfer is not salary. In my opinion, main barriers are Barcelona tactic and their strength to compete for titles. Xavi actually has improved Barcelona a lot in last half of a year but it is not enough to bring Barcelona back to be really competitive in Champions League. Lewandowski after many years as a champions, will not readily to play without chance to fight and win title, in La Liga and in Champions League.
I don't know how possible if the rumors happen and Messi is willing to cut his salary, I think that option is more realistic than bringing Lewa to Camp Nou, I believe the tic tac strategy is more effective when Messi is on a front when compared to Lewandowski. But, nothing change can happen in next month. as we know how the transfer market happens in the last few years, Ronaldo comes back to MU in the last few days after almost closing.
Messi is not happy in Paris and PSG but he has conflict with Laporta and Barcelona does not want to get Messi from PSG. They don't want to pay transfer fee and high salary for Messi. After all drama they created from Bartomeu to Laporta, we can smell their intention to force Messi leaving the club. Maybe they will welcome Messi back in their La Massia or staff, management team or club brand ambassador but not as a player.
Of course, Barcelona has already got a personal agreement with him. Barcelona only needs an agreement about the transfer fees with Bayern Munich. If Barcelona wants to sign him, Barcelona must make a new offer with bigger money. Sadly, we know that Barcelona has limited money. They still have a problem with the financial crisis. In this matter, it is very doubtful that Barcelona wants to make an offer with a bigger amount of money
Personal agreement, is it true? Is it what you guess or what you read on social media? We are not able to verify that the agreement we read is real or just a news on media. In transfer market and media, there are lot of news like that. Some are true and some are untrue.
We only know it is true when a transfer is completed or it is not completed. Like Mbappe transfer and news with Real Madrid. In the end, the transfer did not happen.
