Championship leaders Coventry head into this game as the EFL's only unbeaten side and with a one-point lead over Middlesbrough.
Watford collected their first win under returning boss Javi Gracia when beating West Brom 2-1 on Wednesday but, along with Ipswich, are the only side without an away win in the division.
Coventry City have only lost one of their last 12 league games against Watford (W4 D7) and none of the previous seven encounters (W3 D4).
Since a run of three successive wins between October 2007 and May 2010, Watford are winless on each of their past six league visits to Coventry (D4 L2).
