Alli was brought to Spurs in the summer transfer window, and he has quickly established his place in the side’s starting line-up.
Onomah has watched the 19-year-old’s progress first-hand, and he is now hoping that Mauricio Pochettino offers him a similar route into the senior set-up.
“He’s one year older than me and it just shows if you work hard and take your chances you can get your England debut,” said Onomah. “He’s definitely someone who’s been playing well at the moment.”
Onomah made his Premier League debut for Spurs in their 3-1 victory over Aston Villa, and his introduction highlighted Pochettino’s faith in him.
The youngster was introduced when Spurs were having their worst spell of the match and the result was far from secure, with the scoreline hanging in the balance at 2-1 and with Villa pressing.
However, Onomah showed his manager was right to trust him in a pressurised environment, and he put in an excellent cameo.
The attacking midfielder was composed in possession, and he played a part in Harry Kane’s late goal, which ensured the Lilywhites would claim the three points.
