Harriers’ promotion push has stalled in recent weeks and they have now lost three games in a row following Saturday’s late defeat at struggling Gainsborough Trinity.
Last season’s play-off semi-finalists are still sixth in the table and have a four-point gap to eighth but boss Eustace didn’t hold back after their latest reverse.
He told the club’s website: “I’m disappointed, very disappointed. That’s three defeats in a row and we are going to have to liven up quickly if we are thinking of getting into the play-offs.
“I’m disappointed with the group, we have got a game on Tuesday and we really need a big reaction.
“Nobody is interested in performances, it’s results (that count) at the end of the day and we have had three disappointing defeats.
“I need the group in there to get together, as well as myself and the staff, and we need a positive result on Tuesday.”
