Tottenham manager Antonio Conte says club doctors were "really worried" about his health but he now has "a lot of energy" as he returns to the club.
Conte, 53, had gallbladder surgery last month and, after briefly returning for two matches, has missed Spurs' past four games to recover in Italy.
He will be back in the dugout for his side's Champions League last-16 second leg against AC Milan on Wednesday.
"I have to still recover weight but for the rest I am OK," the Italian said.
"My feeling is good. I have lot of energy.
