Leon Osman believes Ross Barkley needs to add consistency to his game to flourish under Ronald Koeman at Everton.
Ross Barkley must work on delivering on a consistent basis if he is to become a key player for Everton and England, says former team-mate Leon Osman.
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.
