Croydon v Glebe
Balham FC, only formed in 2011, have a home tie in the London Senior Cup Second Round against AFC Wimbledon. They currently groundshare at Colliers Wood United's ground which is only a short distance from Plough Lane (the spiritual home of Wimbledon) and close to Wimbledon Common where the newly formed AFC club famously held trials in June 2002. It's certainly going to be an interesting game for both sides.
The current holders are Cray Valley (PM) who beat the Met Police in the final last season. They have a very local away game against Greenwich Borough who now share the lease of their Badgers Sports Ground in 2016.
The other stand out tie for me is Corinthian Casuals v Dulwich Hamlet which is set to be a great game between two clubs with lots of history. Hamlet last won the cup in 2004 when they beat local rival's Tooting and Mitcham United. Corinthian Casuals have never won the competition but did get to the final in 1957 when they lost to Brigg Sports.
