Manchester United boss Marc Skinner called for changes to the qualification rules and criticised the referee after his side failed to reach the Women's Champions League group stage.
The Women's Super League side were beaten 3-1 in the second leg of their second-round qualifier against Paris Saint-Germain at the Parc des Princes to go out 4-2 on aggregate.
Skinner felt it was a tough draw for United while other clubs may have been given an easier passage.
"It's crazy that we have to play PSG in this qualifying round, crazy," he said.
"It needs to be something that is addressed. Having said that, we will learn from it. We'll come back stronger. We got a taste of it.
"I'm going to make sure we're driven to make sure we are a constant fixture in the Champions League."
United gave themselves hope when Lisa Naalsund cancelled out Lieke Martens' opener to level at 1-1 early in the second half.
