The former Three Lions number one is understood to have been told by Gareth Southgate on Monday that he will not be part of the 23-man party heading to Russian Federation.
Southgate reveals his 23-man squad for the tournament in Russian Federation on Wednesday, the BBC said.
Lineker, who scored 48 goals in 80 games for his country, said these players, alongside those who have enjoyed recent success at junior level, will help England become a "serious force" in four years, when the next World Cup takes place in Qatar. We have got some great young players.
"Ruben Loftus-Cheek, Trent Alexander-Arnold, Ryan Sessegnon, bring them in and give them that little bit of experience".
"(The squad is) all done in my mind and everything's ready to go. It's better for everyone.
Lineker's thinking might actually line up with that of Southgate, who told ESPN FC that the continued development of his team is more important than reaching a certain round of the World Cup.
Arsenal midfielder Jack Wilshere has also been left out in favour of Manchester City's Fabian Delph, sources said ahead of Wednesday's confirmation of the 23-man squad. Wilshere has not played a single minute under Southgate since former England defender took charge on the Three Lions - initially on an interim basis - in September 2016.
