Hazard is a better overall footballer, full-stop. Suddenly Salah has a great season and he's better than Hazard? No.
Since when does one season count more than 4 or 5 years of Hazard being better? He has many more miles to run until he should be considered better. Not to mention, when Hazard was the better player Chelsea won titles, with him as the man. Also, let's be real, Liverpool's style of play is much more suited to Salah than what Chelsea does for Hazard. At least until this season and unsurprisingly Hazard has been a beast in Sarri's system. Best player in the league along with Mane. Not even mentioning the players in the front 3 that each of them had to play last year. Morata/William/Pedro or Mane/Firminho/Coutinho? There is no person on this planet that would chose the Chelsea guys. The difference is huge.
Yeah, Salah has become overrated.
