The Gunners make the short trip across London to the newly-promoted Hornets following the end of the international break.
Arsenal hoisted themselves up to second place in the Premier League table after a 3-0 victory over bitter rivals Manchester United at Emirates Stadium before the international break.
The Spain Under-21 international, who has been a mainstay of Arsene Wenger’s side this season, took to the photo-sharing app to express his excitement ahead of Saturday’s London derby.
Bellerin wrote on his Instagram page: “Looking forward to being back at the Vic tomorrow. S/O @TheLimeBath for the pic.”
The Spaniard played the full 90 minutes as goals from Alexis Sanchez and Mesut Ozil wrapped up a 3-0 victory for the Gunners against Manchester United in north London before the international break to move them up to second in the table.
He has started seven Premier League games for the north London club so far this season and has also featured once in the Champions League.
