Lee Bradbury felt the Hawks lacked intensity and power as they lost 3-1 at Dagenham & Redbridge in the Vanarama National League.
The Hawks boss saw his team well beaten despite a late consolation from Jonah Ayunga.
He said: ‘We just didn’t get out of the traps.
‘They could have been 2-0 up in the first 10 minutes.
‘This was a shock for us.
‘They picked up too many second balls.
‘Our decision making without the ball was nowhere near good enough.
‘We need to be playing with a lot more intensity and power.
‘Their front four were very mobile and quick.
‘We couldn't deal with it at times.
‘I was pleased to see Jonah Ayunga get another goal.
‘It was one of the only times we won a header in their defensive third.
‘They were better than us and deserved to win.’
The visitors made one change to their starting line-up with Andreas Robinson replacing the injured Theo Lewis.
Dagenham started well, while the Hawks had to make a change with the injured Rory Williams replaced by Bradley Tarbuck after only five minutes.
The pressure was relentless and it was no surprise when the home side took a seventh-minute lead.
From a short corner Conor Wilkinson waltzed past two defenders and smashed the ball high into the net from an acute angle.
When the visitors stole a ball deep in the home half Ayunga forced a good diving save from Elliott Justham.
It was soon 2-0 five minutes after the break.
Wilkinson scored with a good shot on the turn from the edge of the area.
The Hawks lifted their tempo in a bid to hit back with Aaron Cosgrave and Tyler Cordner going close.
But on 74 minutes it was 3-0.
Balanta was allowed to run 30 yards through the Hawks defence and net.
Six minutes from the end Ayunga latched onto a long ball over the top and neatly lobbed the ball over the stranded goalkeeper for what proved a consolation goal.
