With Chelsea's history in firing coaches, I don't actually also think he'll last long, he has barely been a coach for two years, with no experience whatsoever, throwing him into the job for me is not a good one for Chelsea, probably they're tryna do the guardiola(when he took over Barca)
Coaches this days are scared to take the Chelsea job, the body just hasn't got no chill, they want immediate success, they forget other top teams also come in fortified ready to compete.
sadly, I can see Chelsea going trophyless again.
