Chelsea is leading the race to sign  Dembele from Barcelona

Press reports revealed that French winger Ousmane Dembele has been linked to Chelsea and received a tempting offer to join the Blues during the current summer transfer market, in a free transfer deal, after the end of his contract with Barcelona. The French newspaper, L'Equipe, said that Dembele had received a strong offer from Chelsea FC with a great salary, which exceeded the offer made by Barcelona to renew his contract. Chelsea has reportedly made a last-ditch attempt to convince Dembele to join with a fresh 'contract offer' which will now prompt a decision to be made imminently with his preference to remain in Spain still well known despite these new developments.
The French newspaper added that Chelsea's offer would be tempting for the French star on the other hand, which is the presence of German coach Thomas Tuchel, who trained with him within the ranks of Borussia Dortmund in the past.
Dembele’s contract with Barca expired at the end of the current season, after spending 5 seasons with the Catalan team, since joining in the summer of 2017 from Dortmund.
