Arsenal manager Jonas Eidevall said it is "a problem for the competition" that not all games played in the Women's Champions League use the same technology.
The Gunners lost 1-0 in the first leg of their quarter-final tie with Bayern Munich on Tuesday despite strong appeals for a penalty in each half.
The video assistant referee (VAR) is introduced in the last eight, while goalline technology is optional.
"We have to accept it," said Eidevall.
