The London Stadium will not be a melting pot of West Ham fans hoping to celebrate a Europa Conference League final triumph - due to a prior agreement with Major League Baseball.
The Hammers face Fiorentina in the European showpiece in Prague on June 7 - as they look to win their first major trophy in 43 years.
With just an allocation of 4,890 at the 20,000 capacity-Fortuna Arena for the final in Prague, there will be plenty of West Ham supporters looking to congregate together to enjoy what could be a momentous occasion.
