The recent terrorist attacks in Paris has all of Europe on a heightened state of alert.
And football in particular is in the spotlight after the France vs Germany match was targeted by bombers in scenes that rocked the world.
Away fans have been banned from all French Ligue 1 matches until at least mid-December as a result.
And increased security measures are being implemented in the Premier League too ahead of the latest round of matches this weekend.
Mass gatherings of people inevitably means extra safety measures.
"With enhanced security checks taking place around the Boleyn Ground for Sunday's game against West Bromwich Albion, supporters are advised to arrive earlier in order to allow time to clear security," West Ham warned on whufc.com.
"As every bag will be checked thoroughly, supporters are therefore advised not to bring any large bags or rucksacks where possible as this will delay their entry."
Upton Park to open earlier than usual
The club has moved to reassure supporters, though, by revealing Upton Park will be open earlier than usual to accommodate the enhanced security checks before the 2.05pm kick off.
"So please arrive earlier than normal to ensure you do not miss kick-off against the Baggies," the statement concludes.
Sad but necessary
The heightened security and sense of fear is a sad state of affairs for people paying good money to watch their team and be entertained for a couple of hours.
But it is necessary given the events of recent weeks.
Times like these usually serve to unite the football family and offers an escape from reality in many respects.
Like in France football is the national sport and fans would rather the authorities implement extra checks so they can watch the game with peace of mind.
