Rosler made six changes to his starting line-up for the southern section quarter-final clash at Roots Hall and he was pleased with the performance, if not the result.
"I am extremely proud of the team I put out," said Rosler.
"With the injuries we currently have, I was happy with the way we started passing the ball and we were very unlucky with the first goal taking a big deflection.
"For the second goal I don't think Kevan Hurst will ever do that again.
"We had three or four big chances before we got the goal back in the second half but overall I cannot fault the players I had on the pitch. We played very well and it is just a testament of the form we are currently in even though we didn't pick up the result we wanted."
