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.
The rules are simple, Barcelona will likely lose again in the next 2-3 seasons if they really want to sign Lewandowski from Bayern Munich. The high asking price of Bayern Munich at this time does not make Barcelona much benefit from Lewandowski. Maybe in terms of performance and the quality of the team will improve, but in terms of business Barcelona will lose big later.
I hope Barcelona prefer to keep De Jong rather than sell him to Manchester United. But if Manchester United don't back down then I hope Barcelona can shift their target to a much younger striker than Lewandowski. But of course it will be difficult because there are other important factors in every transfer of players between teams and maybe that is another part that is in the interest of personal.
I think your expectations about Barcelona and De Jong are already difficult to come true because it seems that the agreement with MU regarding the De Jong issue is only a matter of time for now especially when you look at the current price match and see from their condition that they need money especially in this case Fabrizio Romano have also spoken, it is very likely that an agreement will occur for the next few days.
I also still feel that this will be an interconnected chain when De Jong is agreed so Lewandowski is definitely going to Barcelona.
