Nketiah scored twice and missed a penalty as England U21 thrashed Albania U21 5-0 on Tuesday evening.
The 21-year-old enjoyed a superb European Championship qualifying campaign, becoming England U21s record goalscorer and enhancing his reputation as one of the most talented young players in world football.
‘He’s very good,’ Owen said of Nketiah after England’s emphatic victory over Albania.
‘He’s got a real smell for it, hasn’t he? He knows where the ball’s going to drop. I like his movement. I like his hunger to score goals.
‘Some players are confidence players. If you miss a penalty and you’re a confidence player, you go missing all game.
‘If you’ve just got pure self-belief, it just shrugs off you and you’re just onto the next one.
‘With that type of attitude, with the way he plays, he’s just going to be a goal machine all his career.
‘The key for him is obviously trying to get consistently into that Arsenal team, and then all his horizons are open.’
