Crystal Palace are furious with Arsenal over the manner of their offer for Wilfried Zaha.
The Gunners have offered 40m, which will not even be considered, says BBC Sport.
Palace value Zaha at around 80m and are furious with Arsenal for what they believe to be a ham-fisted attempt to destabilise the Ivorian and secure a cut-price deal.
They would expect a drastically higher fee than the 50m Manchester United paid them for Aaron Wan-Bissaka.
Wan-Bissaka is a 21-year-old right-back with limited experience and no international caps; Zaha is a 26-year-old winger with vast experience and a full international.
Zaha signed a new five-year contract last summer, which recognised his importance to the team and club by making him by far the highest-paid player in Palace history.
