There is a possibility that Barcelona failed to get Raphinha, because Chelsea made a bigger offer to Leeds. Although Raphinha prefers Barcelona
to Chelsea, it is impossible for Leeds to sell Raphinha below the price offered by Chelsea. And it seems with Barcelona's financial condition that is
not good, it is very difficult for Barcelona to compete on price with Chelsea. In the end, extending Dembele's contract is the best option for now
that Barcelona can do, especially since Xavi became Barcelona coach, Xavi managed to make Dembele put out his best performance. So releasing
Dembele to another club for free would be detrimental to Barcelona in my opinion, especially since Barcelona brought in Dembele from Dortmund
at an expensive price. So in the near future it is likely that Barcelona will officially announce the extension of Dembele's contract.
