Watford goalkeeper Richard Lee made a horrendous error to give Charlton a deserved 1-1 draw and ensure the Hornets' dire home form continues.

Lee appeared to dive too far across his goal when Addicks winger Darren Ambrose let fly from the edge of the area on 78 minutes and his shot slipped through his grasp and into the net.

Nathan Ellington's first goal for the club since his club record £3.75million move from West Brom in the summer had looked to be enough to secure Watford's first home win since late October before Ambrose's speculative late strike was fumbled in.

Ellington was handed a rare start in place of Marlon King - whose £5million move to Premier League strugglers Fulham remains ongoing - but was anonymous until latching on to Darius Henderson's pass to stroke home.
