Shrewsbury Town manager Graham Turner has warned his players not to be complacent just because Hereford United are the visitors to the New Gay Meadow next Tuesday.
"Hereford are having a revival and have put in spirited performances at a number of places," Turner told the Shropshire Star.
"They’ve been unbeaten in quite a number of games, certainly since Jamie Pitman took over."
Shrewsbury are currently third in the League and face Southend tomorrow.
"It’s now coming to a tricky time of the season where you get upsets," continued Turner.
"You look sometimes at the tables and think ‘that result should happen here, they’ll win there or they’ll beat them’ and sometimes you get upsets.
"Even at the top level it happens when you get Sunderland winning at Chelsea."
Shrewsbury may be without former Bull Lionel Ainsworth on Tuesday. He is said to be recovering from a groin injury.
