West Ham players reportedly taunted Jose Mourinho during the Chelsea manager's outburst at referee Jon Moss.
Mourinho is accused of verbally abusing Moss during half-time of Chelsea's 2-1 loss to the Hammers at Upton Park on Saturday.
The Mirror is reporting West Ham players who saw the incident taking place reportedly warned Mourinho: "Don't hang around there - it'll cost you another £50,000."
The players were referencing the £50,000 fine and suspended stadium ban issued to Mourinho following his criticism of Premier League referees after a 3-1 loss to Southampton earlier in the season.
