Police are facing a challenge after Wednesday night's Carabao Cup draw set Tottenham and West Ham up for a midweek clash at Wembley Stadium.
The Metropolitan Police will liaise with both Premier League clubs ahead of the fourth-round tie, which is to be played on Tuesday October 25 or Wednesday October 26. A heavy security presence can be expected.
Tottenham can expect to at least treble the 24,000 crowd that went to watch them beat Barnsley, with Dele Alli scoring the only goal of the game on Tuesday.
Spurs and West Ham will likely put out statements in the week before to warn that any trouble will not be tolerated as they aim to avoid the tie being overshadowed by the behaviour of fans.
