West Ham have called in extra security ahead of the Europa League semi-final first leg against Eintracht Frankfurt.
The Hammers are set to take on the German side in the last four of the competition next week.
Frankfurt’s fans essentially invaded the Camp Nou when they beat Barcelona in the second leg of their quarter-final, with 30,000 fans in attendance as their side pulled off a major shock in Spain.
The Daily Mail reports that there are fears over a number of ticketless fans making their way to east London on Thursday so the Hammers have called in extra police officers to try to ensure the game goes off without a hitch.
Discussions are said to have taken place between both clubs, while a number of new stewards will also be drafted in.
It is perhaps the biggest game to be played at the London Stadium since it opened and the Irons are very keen to ensure there are no problems whatsoever on Thursday.
