Sutton United are 16th in the National League, English football’s fifth tier, and play at Gander Green Lane, which has a 5,000 capacity – 55,000 less than Arsenal’s Emirates Stadium.
They have beaten League Two Cheltenham Town, League One AFC Wimbledon and Championship Leeds United to get this far.
Speaking to BBC Radio 5 live, assistant manager Micky Stephens said: “I’ve had to come and sit down, I can’t quite believe that.
“I’m a lifelong Chelsea fan so I had my fingers crossed for that – but it can’t be much better.
“Craig Eastmond and Roarie Deacon have both been involved at Arsenal in their younger days and I’ve never seen them jump up and down as much.
