#1 Luis Enrique
The former Barcelona manager took a sabbatical after he left the Spanish giants in April last year. During his three years with the club, he had helped them to win a Champions League title as well as two La Liga titles.
While he has not spoken of his interest in joining any clubs, there is always a chance that Luis Enrique might be convinced to come to the Premier League and take charge of Chelsea should Conte be replaced.
He has said last year that he was not thinking of joining any other club, but to recover for at least a year. Now that he has been without a club for this long, he may look to get back in the game. His style of play is similar to that of Chelsea, and the team might suit the manager well. Both have a defensive attitude with short passes and a counter-attacking style.
Al that it remains now, is for Chelsea to be able to convince him to join them before any other club approaches him.
