Crystal Palace chairman Steve Parish is fed-up with Manchester United's negotiating tactics over Aaron Wan-Bissaka.
The Daily Star says Palace have told Manchester United to stump up £60m - or forget about signing Wan-Bissaka.
Parish is losing patience with United over their pursuit of the England U21 international.
United have made two bids for the full back totalling £40m and are reluctant to meet the asking price in full.
It is understood United executive vice chairman Ed Woodward's latest bid of £40m also included several add-ons that infuriated Parish.
Palace are demanding £60m in one go and will refuse to sell the defender unless United offer what they want.
