The 19-year-old made his competitive debut for Spurs against Manchester United on Saturday, coming on for the last 13 minutes of the match after replacing Eric Dier.
The latter may be more commonly known as a defender but he started Saturday’s match in midfield in the absence of Ryan Mason. But the experiment did not work, with United going on to win the match 1-0 courtesy of an own-goal from Tottenham's Kyle Walker.
Alli impressed in recent pre-season matches against MLS All-Stars and Real Madrid and he has not had to wait long to get his first taste of Premier League action, even if Waddle is not convinced he will be an instant success.
Waddle made 138 appearances for Tottenham and speaking on BBC Radio 5 Live shortly after Alli came on, he said, “I’ve seen bits of Dele Alli. He’s a big strong lad and he can score. But this is a big step from where he’s been playing.”
That it is, with Alli playing last season in League One with MK Dons, where he ended the campaign with 16 goals and 11 assists.
It was his good form that encouraged Tottenham to make a £5million move back in January, but it seems Waddle is warning against the club’s fans putting too much pressure on Alli too soon.
