Arsenal pair Dani Ceballos and Eddie Nketiah clashed in the warm-up before today's Premier League opener against Fulham.
During a small-sided 'rondo' game, Ceballos appeared to become frustrated and put in a heavy challenge on the young striker.
The two appeared to have some strong words and then square up to each other as things almost came to blows.
A couple nearby Arsenal players intervened and walked Nketiah away from the clearly outraged Ceballos.
