Brighton and Hove Albion have been facing off in negotiations all summer, on Saturday they meet on the field for the first time this season.

The match is being played at the Lincoln Financial Field this Saturday with a midnight BST kick-off.
Seagulls fans will be hoping to catch a glimpse of new signings James Milner and Joao Pedro.
