Jones thrilled following first win
London Welsh head coach Lyn Jones was delighted with his side after a spirited performance secured their first Aviva Premiership victory in an encounter with Exeter that finished 25-24.
With less than two minutes left, number eight Ed Jackson rounded off a last desperate surge by forcing his way over for the try which replacement fly-half Seb Jewell converted to win the match.
Welsh were heavily beaten in their opening two matches and Jones said: "We are delighted not just with the result but the performance was so much better. We didn't fold, we kept in there and took our opportunities. We showed a lot of character to come back."
He added: "Two weeks seems a very long time ago since we played Leicester here and were found wanting.
"After having such a tough time against Leicester and at Harlequins, we've learned a lot about ourselves."
But he knows his side are still a work in progress.
"We don't really know where we are yet. We have some players who haven't been in England for four weeks yet," he said.
"We're a feisty bunch but it does take time. It was important we grew as a team and the win over Exeter, who are a very strong well-drilled side, should improve our confidence."
Exeter director of rugby Rob Baxter, whose side have shocked a number of big-name teams since their promotion to the Premiership in 2010, said: "We won't be calling a crisis meeting on Monday or calling players in for extra training. I think today's more about congratulating London Welsh than worrying about what we did wrong.
"We'll just learn from the things we did wrong, as we do after any other game, and move on."
