Watford's last away match at Derby County ended with 12 corners in total. 2 more matches from their last 5 trips have had at least 10 corners, at Bramall Lane against Sheffield United, 10 corners were produced and 11 at Coventry City. 4 of Birmingham City's last 5 home matches have seen over 10 corners, 14 against Sheffield Wednesday, 16 against Hull, 14 against Portsmouth and 11 against Norwich. Watford's last visit here was in the 2023/24 season which ended with 13 corners, so over 10.5 looks a decent shout out.
