Watford will look to extend their undefeated run to a sixth league game as they make the trip to Birmingham City on Monday (20:00 GMT).
The Hornets have only lost two games since boss Javi Gracia took charge in October (W3 D3), placing them three points short of the top six.
Blues, however, are also chasing a spot in the top six and have won five of their eight home games so far this season (D2 L1).
Birmingham City have lost 10 of their previous 12 league games against Watford (W1 D1), and failed to win any of the last seven (D1 L6).
