The Football Association have written to Harvey Elliott after the Liverpool midfielder was seen holding a flare following the Carabao Cup final win over Chelsea.
The Reds beat the Londoners 11-10 in a dramatic penalty shootout at Wembley on Sunday after a 0-0 draw across 120 minutes.
In the celebrations Elliott could be seen walking around the pitch with a red smoke flare as the Liverpool players and coaching staff toasted to the success in front of around 33,000 fans at the national stadium.
