Osterley's players have been forced to conduct an inquest ahead of the biggest game in the club's history this Sunday.
Asad Rizvi's men face Surrey Championship Premier League side Wimbledon in the quarterfinals of the Evening Standard Cup, where victory will put them just one match from a final at the Oval.
But they'll have to produce a quick turnaround in form after what Rizvi termed 'the most disastrous weekend I can remember at the club'.
He said: "We had something of a heart-to-heart, we knew they'd let ourselves and the club down, but we're feeling more positive now. Wimbledon will be tough, but we've beaten Premier Division sides from the Surrey Championship before."
Osterley's problems began on Saturday when they suffered a huge batting collapse in a 133-run defeat to MSTCC in the Middlesex Championship. Chasing 252 to win, they were 105-2 when Abid Ahmat fell for a well made half-century.
In-form batsman Ashraf Ali fell first ball and wicketkeeper-batsman Mohammed Qaisar became a hat-trick victim before Rizvi, who had watched the carnage from the other end, perished for 40 as eight wickets fell for just 12 runs.
Sunday's Middlesex Cup clash with Hampstead was a similar sorry story.
Half-centuries from Ali, Ashraf and Qaisar left Osterley needing 40 off the last 10 overs with five wickets in hand. But panic set in and three runouts saw them lose by five runs in the last over.
