England coach Eddie Jones believes rugby union should look to football if the game wants to improve its skill level.
Jones visited Newcastle United's academy on Tuesday morning, giving advice to youngsters at what he described as "one of the greatest football clubs in England."
But the Australian, who has rejuvenated the national team since taking over from Stuart Lancaster in 2015, made it clear the education was not one way. He suggested that skills in rugby had not improved since the dawn of professionalism, 20 years ago.
"There are things we can learn from in football, and possibly vice versa," Jones told Newcastle's official website.
"The thing that impresses me about football, and really hasn't happened in rugby so much, is that the players are individually highly skilled.
"Rugby has improved a lot -- having only been professional for 20 years -- but the skill level has not improved so much and that is something which really interests me.
"I think there's always a bit of rivalry between the two sports, which is healthy but certainly I think we can learn a lot about skill acquisition and skill development, particularly the individual skills of players."
Jones' England will face Argentina, Australia and Samoa during November's autumn internationals as they continue to build towards the 2019 Rugby World Cup.
