The 21-year-old made the big-money switch from Norwich City to Leicester in the summer transfer window.
Maddison has scored or assisted an impressive four goals in his first six appearances in England's top division, after moving to Leicester from Norwich City for a reported fee of around £25 million in the summer transfer window.
And according to Collymore, who played for the Foxes at the start of the millennium, the 21-year-old's swift ascent could before long lead to international recognition.
"There's no youngster more exciting in the Premier League right now than Leicester's James Maddison", wrote Collymore in his column for the Daily Mirror (September 25, page 51).
"Maddison is dynamic, creative and even has a little bit of cockiness about him."
"It's all there for him, now he just needs to show his durability for Leicester and then hope Gareth Southgate rewards him with a run of games in the England team that will allow him to bed in there as well."
Maddison had scarcely featured at Championship level prior to last term, but scored or assisted 22 goals in 44 appearances to be named Norwich's Player of the Season and earn a nomination for the Championship's Young Player award.
The Coventry City academy product, who has four caps for England's Under-21s, was signed to fill the void left by Riyad Mahrez at Leicester, after the Algerian to Manchester City following a lengthy pursuit.
