Everton fans threatened to "riot" if the club cash in on teenage winger Harrison Armstrong.
England under-19 international Armstrong was reportedly the subject of a £40million offer from Premier League rivals Nottingham Forest ahead of Saturday afternoon's game away to Bournemouth.
The 19-year-old academy graduate started for the Toffees at the Vitality Stadium to make his 24th appearance for the club.
Travelling supporters made their feelings clear on the situation, repeatedly chanting: "Don't sell Armstrong, Harrison Armstrong, I just don't think you understand. If you sell Armstrong, Harrison Armstrong, you're going to have a riot on your hands."
Armstrong spent the first half of last term on loan to Preston before being recalled in January. He previously had a temporary spell with Derby.
Everton have a history of selling their top homegrown talent.
Wayne Rooney moved to Manchester United in 2004 before Ross Barkley joined Chelsea in 2018 and and Anthony Gordon left for Newcastle in 2023.
Going further back, defender Michael Ball departed for Rangers in 2001, while striker Francis Jeffers was sold to Arsenal in the same year.
