Furious Leeds United supporters plan to protest against the sale of midfielder Aaron Lennon to Tottenham for £1m.
The 18-year-old will complete his move to White Hart Lane once he agrees personal terms and passes a medical.
Leeds fans are upset with chairman Ken Bates, who they believe pledged to stop the sale of their young players.
"We aim to make our feelings known because we thought the sales would stop but nothing has changed," said a Leeds United Supporters Group spokesman.
