Alex Pike was disappointed that Gosport Borough returned from Truro City with just a point following their 2-2 draw in the Vanarama League South.
All the goals came in the first half, and the Privett Park boss believes his side should have gone on to win the game.
‘I view it as two valuable points dropped,’ said Pike.
‘We were our own worst enemies with both the goals we conceded being very sloppy.
‘Their (Truro’s) first goal came from a set-piece and the second from an individual error.
‘It was very disappointing because when we scored on the stroke of half-time I thought that would act as an arrow through Truro’s heart.
‘The elements were in our favour in the second 45 minutes and I expected us to push on and win.
‘In fairness, though, for the final 20 minutes our game management was poor and Truro threw the kitchen sink at us.’
Borough fell behind after eight minutes when they failed to pick up Jamie Richards, who headed in unmarked from a corner.
The visitors equalised nine minutes later through a Justin Bennett penalty, after Rowan Vine had been pushed inside the area.
But almost immediately a howler from goalkeeper Nathan Ashmore gifted the home side a lead for the second time.
Rory Williams headed the ball back to the keeper but he completely missed his clearance kick, allowing Jamie Reid to score.
Borough continued to look dangerous, though, and recent-signing Vine levelled on the stroke of half-time.
‘I have been really pleased with Rowan since he joined us,’ added Pike.
‘He looks like forming an excellent partnership with Justin Bennett up front.
‘It is only his second game for us and he hasn’t played a lot of football.
‘He will only get stronger and is starting to look like a Football League player who cost £3m at one time in his career.
‘I expect him to get better and better and he hasn’t cost us a penny.
‘Justin Bennett has now scored 13 goals in as many games and Rowan created the last two for him.’
Borough had chances in the second half to win the game.
Bennett skimmed a header against the top of the crossbar and Vine fired wide after beating City’s offside trap.
The visitors had a late let off when a quickly-taken free-kick by Reid bounced back off the post.
Pike said: ‘With all due respect to Truro, if we are to challenge for the play-offs these are the sort of games you need to be winning.
‘The fact we didn’t push on in the second half and do that was hugely disappointing.
‘At the same time, it is crucial that we cut out individual errors which are costing us.’
