Well, tis rumor is riisng up again significantly. Although actually, Mbappe's wish is for Real Madrid. However, this also does not rule out the possibility for him to join one of the big clubs in the Premier League. As you know, last season, Chelsea's performance was really very low and bad. So they really need star players to strengthen their team and compete again with the top EPL clubs.
On the one hand, mbappe might want to join Chelsea but on condition that it is only a loan player, not a permanent purchase. This news will certainly surprise many parties, especially Real Madrid, who have been eyeing Mbappe for a long time.
