One of Leeds United's former players has had his say on arguably the club's most talented current youngster.
In an exclusive interview with the site, the one-time Leeds defender explained just how far he thinks Cook can go in the game.
Parker made just 41 appearances for Leeds during a seven-year stint at the club, but he will have seen Cook come through the ranks and he is effusive in his praise for the 18-year-old.
“The worst kept secret coming out of Leeds is Lewis Cook,” Parker said.
“He’s got a fantastic future ahead of him and he reminds me a little of Fabian Delph in a way.
“It would be no surprise if he (Cook) gets England honours in the future and is playing at the top end of the Premier League because he’s got the quality to take him all the way.”
Cook has played 38 senior matches in his debut campaign for Leeds, providing two assists in that time and looking every inch a star-in-the-making.
He has also earned a call-up to England’s under-19 side, but it was on international duty that he suffered an ankle injury that ended his season prematurely.
That said, there are still huge positives to take from Cook’s progress, and at just 18 he is already one of the first names on the Leeds team-sheet.
The question is: Will he be playing in the top flight with his current club or another side further down the line?
For United and all their supporters, hopefully it is the former.
