Ross Barkley must work on delivering on a consistent basis if he is to become a key player for Everton and England, says former teammate Leon Osman.
'Henderson better than Pogba currently'
The 22-year-old has not featured in the last two international squads despite being a regular at Goodison Park this season.
Barkley has started all seven Premier League games under Ronald Koeman, but he has only managed one goal and one assist, a tally not deemed enough by Sam Allardyce and latterly Gareth Southgate.
Osman believes Barkley's troubles stem from the change of manager at Everton during the close season, but he is confident the midfielder will start to improve once he adapts to Koeman's style.
