Sold Campbell feels it is too early to call Tottenham midfielder, Dele Alli, a world class player and considers him a prospect.
Alli has scored seven goals so far for Tottenham and opened his international account in his England debut against France in November.
The former defender, would rather wait for Alli to be consistent, before branding him world class.
“He does look a real prospect, but it is very early stages for him,” he wrote for Sportlobster. “I don’t really want to know about a player until five or six years down the line and I can see their consistency.
“Anyone can have a good season or two – I want to see five, 10, 15 years of quality from a player to be able to call him ‘world class’.
“We have seen players light up this league before for two or three years and then drop off and fade away. I am not saying Dele Alli will do that, but he needs to keep going.
“Hopefully he has a good mentality that will allow him to have the same sort of career [Steven] Gerrard and [Frank] Lampard enjoyed in the Premier League. It would, of course, be great for England if he could.”
