Blues lost an even Barclays FA Women's Super League contest 1-0 with Lucy Staniforth hitting the underside of the crossbar before 'keeper Courtney Brosnan scrambled to safety 10 minutes from the end.
There were other close calls for Staniforth and Sarah Mayling went close on her 50th appearance for the Club but there was no cancelling out Adriana Leon’s 27th-minute finish at Rush Green.
“I am pretty much happy with the performance, not the outcome,” said Tejedor.
“I think we played good football and in my opinion got better and better, at the end every chance was at the same goal.
“We had control of the match but again were not able to score. That has been our biggest problem since the beginning and is our issue right now.
“If we could have got something from the chances we created it would have been very different.”
Blues appeared convinced the ball had crossed the line as Staniforth’s 80th-minute swinging shot came down off the woodwork via Brosnan’s glove.
“I could not see it but did see the assistant (referee) was in the corner and in line so I guess he saw it better than us,” said Tejedor.
“Maybe I can get my own opinion when I see the video but it would not be fair for me to say what it was.”
Tejedor rounded off by expressing belief that Blues will soon see some reward for their efforts.
“We are resetting the team, there is room for improvement with half of the team being new players,” she added.
“We need some time but feel pretty sure we will get better and better. There is no reason for them not to be confident in each other.
“Understanding a team sport is working together towards the same goals.
“The general feeling is that we are disappointed with the result but happy and proud because of the way we played and I am very confident we will start getting points as we continue working.”
