Whitley Bay Ian Chandler was not happy with the way his side started against Seaham Red Star on Saturday.
The Seahorses never recovered from conceding two goals inside the opening 14 minutes as the visitors ran out 2-0 winners at Hillheads.
Chandler said: “It was disappointing, a very poor first 20 minutes. We switched off twice; they were two sloppy goals that we should have prevented.
“In the first half I think they wanted it a bit more than we did, but there was nothing that they had that should have worried us really, but the two goals were preventable.
“We didn’t really create much. We missed Chris [McDonald], Callum [Anderson] and [Michael] Laws.
“We didn’t have a natural left player. We put Callum Munro there and he’s done OK in that position at Durham but was exposed a bit today.”
With regard to his new goalkeeper, Tom Flynn, the boss added: “I think Tom was trying a bit too hard early on, and a couple of times the ball slipped out of his hands, but he’ll be OK.
“In the second half we were a bit more urgent, Alex [Kempster] got down the left a few times, we had about half a dozen shots.
“We had chances, and some half chances and breakaways, so we looked a bit more like what we’ve been used to of late, but Ash Davis and Adam Shanks were off their game and there wasn’t much depth on the bench.
“Anderson, Youldon and Laws were suffering with knocks. Prosser came on and did well. He put himself about ... but the trouble was we gave two goals away and couldn’t recover.”
