Missed chances and defensive slip-ups saw Farnborough go down 3-2 at Wheatsheaf Park in Skrill Conference South
Angry Spencer Day ripped into his players after Farnborough's 3-2 defeat at Staines Town, the hosts maintaining their 100% home record while Day's men spurned a wonderful opportunity to wreck that statistic.
Failures at both ends of the park caused much of their downfall and the visitors simply did not capitalise on the ideal start given to them by Reece Connolly, who thumped them in front from the edge of the box on 12 minutes.
Nathan Koo-Boothe missed a sitter though and after Swans' striker Louie Theophanous poached two goals against the run of play, Connolly blazed a volley over from eight yards out when he had time to control and finish.
Behind at half time, Ollie Treacher then handballed in the penalty area midway through the second half, handing the initiative to Staines who were resting on their laurels at the time.
It allowed Theophanous to grab his hat-trick from the spot to put the hosts 3-1 ahead before the Swans went to sleep again, Boro poaching a second when substitute Andy Mensah poked home the rebound for his first ever senior goal after Dave Tarpey's effort had been parried.
Boro could not force an equaliser, even though they came mighty close three minutes from time when Dan Bennett's fleet-footed trickery and snap shot forced a brilliant response from keeper Kyle Merson.
'Really bad goals'
Day was without injured Elvis Hammond (ribs) while centre-backs Alan Inns and Alfred Bosch made themselves unavailable through work.
The pair riled Day by missing the clash and he had some stern words to level at some of the others in his team.
“We should have been 3-0 [ahead] before they scored,” said Day, whose players became the first Boro side in 40 years to go down to the Swans.
“We conceded three really bad goals and you can see when we are missing key players we don't have the strength in depth.
“I'm not taking anything away from Staines but we changed the system at half time and I thought we dominated and they were sitting on the counter.
“They've then hit a terrible corner in and we've managed to contrive under no pressure to give away a penalty.
"And suddenly we are 3-1 down. A few of our heads went down which is disappointing because we got back into it and but for a fantastic save we would have got a point.”
He added: “I'm really angry about it. At times we tore them apart but we were not being ruthless enough in front of goal.
"We do entertain people, we do play a fluent game and don't believe in parking the bus but we are Jekyll and Hyde defensively.
“It's painful because it's another opportunity lost. If we want to compete at the top end, we are going to have to cut out silly errors.
“I'm angry with the way we started, I'm angry about a couple of people who have let me down when they seemed to think at 3-1 the game was over, when it wasn't, and I'm angry with the two players who were absent.
"It's both ends, you can't miss the amount of chances we are missing and defend as badly as we are and get points out of games at this level. We let ourselves down and when you look back how we lost that game, it is very harsh.”
Donnelly conceded: “I don't think we deserved to lose but we missed chances including me and it came down to not taking them.
"We could have buried them in the first half. The three goals we conceded weren't the best. We're disappointed because we know we are better than that.”
