The Tottenham boss has sung the praises of the 18-year-old.
The 18-year-old has been on the fringes of the Spurs first team this season but a chance to show the White Hart Lane faithful his abilities in a 4-1 win over Monaco in the Europa League on Thursday night.
The Lilywhites have been an impressive side this season, with the core of their team a young English contingent.
The likes of Kyle Walker, Harry Kane, Dele Alli, Ryan Mason, Eric Dier and Andros Townsend have all matured at the North London club and been selected to represent the Three Lions.
Pochettino has stated that Onomah has a bright future in the game and could well be the next Spurs youngster to feature for the national side.
“Why not? It is impossible to set the limit for him as he is 18 and is very strong,” the Argentine responded when asked if Onomah was a future international, as reported by The Daily Mail.
“His quality is amazing and he only needs to work hard and then he'll be fine.
“He is a special boy, a special player, because of his talent, his potential and his body. His body is powerful and he has quality in his feet. I don't know how he will develop.”
Onomah will hope to play a part in Spurs’ clash with Newcastle in the Premier League today but has stern competition for a starting berth in the London side.
He has already represented England at under-16, 17, 18 and 19 levels.
