Manchester City boss Andree Jeglertz has called for the introduction of video assistant referee (VAR) technology in the Women's Super League
WSL leaders City saw their 13-game winning streak ended by a 1-0 defeat by Arsenal on Sunday, but remain eight points clear at the top of the table.
City felt Gunners midfielder Mariona Caldentey should have been sent off in the second half for bringing down Lauren Hemp just outside the penalty area with only goalkeeper Daphne van Domselaar to beat.
Referee Abigail Byrne judged Caldentey won the ball and waved play on.
"I've seen pictures from different angles and for me, it's very clear it is the wrong decision," Jeglertz said before his side's WSL match against Leicester City on Friday (13 February, 19:00 GMT).
"We can't do anything about it now. As long as the players are working to develop, I'm pretty sure the referees are working to develop. I'm sure in the future we will develop the game in that way.
"I think VAR should be [introduced]. I know there are some challenges with that, but it should be in our league because it's the most fair way for these situations."
Arsenal manager Renee Slegers called for the introduction of VAR in November after her side had an equaliser against Chelsea incorrectly disallowed for handball.
