Roberto De Zerbi said troubled Tottenham cannot afford to cry about their debilitating injury list as they battle to avoid relegation from the Premier League.
De Zerbi's side ended a 118-day wait for a league win at already-relegated Wolves last weekend, but lost Xavi Simons and Dominic Solanke to injuries in the process.
Tottenham are stuck in the relegation zone, two points adrift of safety, with only four games left to save themselves from the humiliation of playing in the second tier for the first time since 1977-78.
"It is not the best moment for us, it is a tough and difficult moment," De Zerbi said ahead of Sunday's trip to Aston Villa.
"But the losers cry, the losers think negative. I don't want people close to me to be crying or think in a different way from me."
Europa League semifinalists Villa can secure a top-five finish and Champions League qualification this weekend if results go their way.
But De Zerbi insisted Tottenham do not need "a miracle" at Villa Park, given the quality he still has at his disposal.
-- NIGERIA ONLY --
"We go to play against one of the best teams at the moment in the Premier League. I have big respect for (Unai) Emery as a coach, but if Tottenham win in Villa Park, it is not a miracle," the Italian said.
"We have to be positive and (feel) lucky because we are working in a big club.
"If Solanke and Simons are injured, we can play with (Randal) Kolo Muani, (Mathys) Tel, Richarlison and they are not worse players. They are different with characteristics, but very good players."
MADDISON TO PLAY A PART
De Zerbi confirmed goalkeeper Guglielmo Vicario remains absent after a hernia operation, while Cristian Romero, Mohammed Kudus and Dejan Kulusevski are also sidelined.
The Tottenham boss is hopeful James Maddison can play a part in the final weeks of the season.
The midfielder has been included on the bench for the past two games but is yet to make his first appearance since suffering an anterior cruciate ligament tear in pre-season.
"I would like to play with him because he is a special player, but we have to consider the physical condition and a lot of things," said De Zerbi.
"But I think he can be important in the next (last) three games."
