Ian Dunn described his Boston Town side as ‘simply not good enough’ after their 3-1 defeat to Cogenhoe.
The Poachers spent the summer strengthening their squad, and have high hopes for the UCL Premier campaign.
However, Dunn was left fuming following their opening day defeat at Tattershall Road.
He said: “We didn’t work as hard as them.
“I felt we had some players that were lazy at times.
“We made three basic errors for the goals that you can’t afford to make at this level.
“That performance was simply not good enough.”
After going down 3-0 to the Cooks, Josh Ford pulled one back for Town from the penalty spot.
But that wasn’t enough for the boss, who added: “We need to be more clinical in front of goal if we want to finish where we’re capable of.
“You get out what you put in and we got exactly what we deserved - nothing.”
