For professional footballers the important location is the training ground and not the main stadium. In Chelsea’s case that is Chobham. Arsenal’s is at London Colney just south of the M25 to the north of London. Tottenham’s is just on the East to the north of Enfield. Geographically it is a mile from where I used to live in the 1960’s.
I don’t think he will be going to either of these two.
