Arsenal boss Arsene Wenger has said his opposition to the away goals rule is not an excuse for his side's exit from the Champions League.
The rule accounted for both Chelsea and Arsenal in the round of 16, with the Gunners conceding what turned out to be a decisive third in stoppage time as they lost the first leg 3-1 at the Emirates Stadium.
They won 2-0 in Monaco to draw the tie 3-3, but went out on away goals.
Wenger is certain the advantage given to away goals weighting in the knock-out stages needs addressing, and believes a move to scrap the rule would have the support of Europe's elite coaches.
He claims the rule encourages home teams not to attack as they look to protect a vital clean sheet.
Wenger has lobbied for change at UEFA's conference for European national coaches but accepts that, until there is unilateral agreement, teams will have to get on with finding a way to deal with perceived negative tactics.
A proposed change to the use of away goals has the support of FIFA president Sepp Blatter.
"I accept the verdict, the rule is the rule and we have lost. We have to be better than the rules. That is not a debate I want to create because we lost," Wenger said.
"We were not good enough to win [against Monaco] and we have to accept that. We have to be strong enough to adapt to the rules, but it is a debate that exists.
"I brought this up at the manager's meeting in Geneva for two or three years. At the meetings, it is split. You could still keep the rule in extra time [but then] people say: 'We still have another 30 minutes to play away from home.' It will still be a little disadvantage, that is for sure.
"Two teams [Chelsea and Arsenal] have gone out on away goals, which I think should be questioned because it is a rule that is outdated now and that has to be changed, and I have fought for that for a long time."
