Oxford United Ladies coach Les Taylor said he was satisfied with his side's performance despite their 3-0 defeat to London Bees.
It was Oxford's season opener of the revamped FA Women's Super League Two.
In addition to a top division of eight teams, this season will see a second tier of 10 teams, with promotion and relegation between WSL 1 and WSL 2.
"I thought they performed really well for long stages of the game," Taylor told BBC Radio Oxford.
Taylor added: "We created loads of chances but all that was missing was a goal.
"They've had five chances and scored three and every one of those you could put down to a mistake.
"Every player had a chance on goal but we couldn't hit a barn door. I'd been worried if we weren't creating chances, we just lacked composure."
Oxford next take on Doncaster Rovers Belles and Taylor has urged his side to rise to the challenge against a team he believes are one the favourites in the division.
"If we create as many opportunities as we did tonight and score then we have a chance," he added.
