The Argentine manager minced no words to express that Madueke has to step up his game to force his way into the starting XI.
Speaking to reporters, Pochettino said: "I think from the beginning of the season, he was involved, then not involved, injured, and suffered some problem. Noni is in a position where there is massive competition, there is too many players in that area.
"I think he needs to compete and improve his level. I think at the moment, he was injured, but now he has recovered, he may be involved in the next games."
