​Millwall are likely to receive a fine worth hundreds of thousands of pounds after their victory over Leicester in the FA Cup was marred by scenes of violence and intimidation at the Den, as the ​Mail reports.

The Lions' biggest rivals are ​West Ham rather than Leicester (who are nowhere near them geographically), but that failed to stop the usual hooligans who tarnish ​Millwall's reputation from ruining the scenes for everyone. Leicester were forced to complain to the FA in a sad aftermath.

Millwall scored a winner in the last minute of normal time to progress through to the quarter finals of the FA Cup, but overexcitement clearly hit and mounted police had to intervene in ugly scenes after the final whistle.

​Leicester report that fans spat at and abused them as they left the team bus and warmed up, that one of their fan coaches had its windows smashed, that missiles were thrown at them and that a mob of home fans attempted to force its way into the away end to attack them.

Missiles were thrown at them by the Foxes fans as well. Sadly, however, the peaceful and cooperative members of the Millwall fanbase will always be forgotten about as a minority attempt to ruin the experience for everybody over and over again. The players cannot be at fault either, as they fought within the rules of the game to beat Leicester.

London's police will be dreading Millwall's next encounter in the FA Cup, against fellow Londoners Spurs. Thankfully, the game is being held at White Hart Lane and the Millwall troublemakers will thus be fewer in number.

Again, Spurs are not Millwall's biggest rivals - but you can bet that thugs will take any excuse for a fight on the day.
