Play-off chasing Watford host struggling Cardiff City at Vicarage Road on Sunday.
Victory over Portsmouth on Boxing Day took the Hornets up to sixth in the Championship table, while a pair of late goals were not enough to rescue a point for the Bluebirds - who are second from bottom - against fellow relegation battlers Oxford United.
Watford have lost their last three home league games against Cardiff City and have only won two of their last 11 against them at Vicarage Road (D4 L5).
