The club decided to press ahead with surgery after initially leaving the France international’s elbow to heal naturally after he dislocated it when landed awkwardly against Brighton on October 5.
“I didn’t see him in the last week because I wasn’t here,” Pochettino said. “But he is strong, he is very mature, he’s a man.
“Of course he is suffering now a little bit but he is going to come strong again. It’s not a problem.”
The hope is that the change of treatment will result in a delays of weeks rather than months and Tottenham assistant manager Jesus Perez fleshed out some of the medical details.
“Apparently surgery has delayed his return, yes, but we’ll see,” he said.
“They went for another opinion after a few weeks, about just how it was healing. Because he is our keeper, they needed to repair something in his elbow and that’s why it may take a little bit longer. But we don’t yet.
“We had expected him to be back by January to train but, now it depends.”
Tottenham entertain Sheffield United looking for their first back-to-back wins since April to kick-start their diminishing hopes of climbing back into top-four contention.
“It’s still there, it’s still possible,” Pochettino insisted. “But we cannot move the club forward quickly, to accelerate things, we can’t.
“It is a natural process, all we can do is stay calm and work hard because there is not another way to change this dynamic.
“We cannot accelerate the time. The time is the time and the process is the process.”
Probable Tottenham team (4-2-3-1): Gazanigga; Aurier, Alderweireld, Sanchez, Davies; Winks, Ndombele; Son, Eriksen, Alli; Kane.
