Ross Barkley can be an England game-changer in Brazil this summer.
That's the opinion of former Everton and Three Lions midfielder Peter Reid.
Barkley was named in Roy Hodgson's 23-man squad for this summer's tournament on Monday.
And Reid believes the 20-year-old is more than deserving of a chance to transfer his impressive club form onto the biggest stage.
"I think Ross has got fantastic ability in terms of going past people, making and scoring goals, and I think he's had an exceptional season," the 1986 World Cup star told evertonfc.com.
"I did think early on in the season his final ball and finishing wasn't up to the top level, but I think he's improved on that and against Manchester City earlier this month, against a top-class side, I thought the kid was absolutely outstanding.
"He's got a pace and a body strength that I like in players and he's one of those lads who can turn defence into attack very quickly with his running power. He does that ever so well. With his improvements in the final third, he can change games.
"You don't get in any England squad or World Cup squad without deserving it. And you never know in World Cups, once you get in that side and you get a chance, with his ability, he could be a real star."
Baines and Jagielka played a major part in England's qualification campaign, making seven appearances each as the Three Lions topped their group ahead of Ukraine.
The pair are both now heading for their second successive major international tournament and Reid believes they do so as established first-team choices.
"Baines has been brilliant for the last two years and, as an attacking full-back, I don't think there's any better," he said. "You've got a mature and confident player there, who accepts responsibility, who's got a lot of experience and is one of those players who every time he puts a shirt on, you know you're going to get a performance.
"As for Jagielka, I think him and Cahill will start. I think they've been really good together and what I like about Jagielka is that he reads the game well.
"You don't see him doing a lot of last-ditch tackles because he usually reads the situation and cuts it off at source. I think he's been absolutely fantastic."
