We were easily able to travel by tube to the Emirates Stadium for the Saturday match between Arsenal and West Bromwich Albion. But when it was time to return, the closest tube station on Holloway Road was closed. I have no idea why. Luckily, our son knew how to get to the closest Overground station at Highbury & Islington, then negotiate the change from Dalston Kingsland to Dalston Junction so we could get off at Whitechapel station. If you attend an Arsenal game getting there by tube, be sure to figure out alternative routes back just in case you encounter a closed tube station.
