Police will take no action after Crystal Palace manager Patrick Vieira was involved in an altercation with a fan following the defeat by Everton on Thursday.
Everton completed a 3-2 comeback win, which led to thousands of fans invading the pitch at full-time.
During that pitch invasion, Vieira appeared to aim a kick at a fan after being taunted by him.
Police spoke to both Vieira and the fan during an investigation.
Merseyside Police said: "We worked with Everton FC to gather all available CCTV footage and spoke to witnesses.
"Officers have spoken to both men involved and the opportunity to make a formal complaint or support a prosecution was declined.
