LIVERPOOL: Crystal Palace manager Patrick Vieira was involved in a confrontation with a supporter after their Premier League defeat at Everton, prompting police and the Football Association to investigate.
Viera was taunted by an Everton fan as fans poured onto the pitch at full-time.
The Frenchman seemed to kick the Everton supporter before being led away by other fans.
According to police, no formal complaint has been filed about the event.
"Merseyside Police is investigating an altercation on the pitch at Goodison Park following the Everton v Crystal Palace match on Thursday," a statement read.
"We are working with Everton to gather all available CCTV footage and are speaking to witnesses. No formal complaint has been received, and enquiries into the incident are ongoing," it added.
Meanwhile, when asked about the incident post-match, Viera said: "I have nothing to say about that."
Everton, on Thursday, bounced back from a two-goal deficit to beat Viera's Crystal Palace to stay in the Premier League.
