The Reds were blown away 4-1 by the Gunners in the Premier League on Saturday, but the Belgian keeper says he and his side are working hard to tighten up ahead of their FA Cup Sixth Round Replay at Blackburn Rovers on Wednesday.
"I always speak to the defence and on the way back from Arsenal we talked through a couple of things," Mignolet told Liverpoolfc.com.

"The good thing is that if there is a game coming so close afterwards, you can go into that game looking forward to making sure that you put things right.
"It's a massive game against Blackburn. It's not going to be easy and it's going to be a totally different game to the one away at Arsenal.
"It will be tough, but we want to get through to the next round and put in a performance to make sure that we play in the semi-final at Wembley."
Having conceded four at the Emirates, Mignolet admits to being his own biggest critic, but he says he is constantly working hard on becoming a leader at the back.
"I'm my own biggest critic and you analyse your games in a critical way together with the goalkeeping coach. You see afterwards what you could have done better," he added.
"The goalkeeping coach, the gaffer and the fans asked me to be commanding and demanding.
"I've done that ever since I came back into the team, to be loud and help the team out, organising and helping them in a positive way.
"Organising the defence is something that is very important and I try to do my best every single day in training to make sure the lads get the information they need."
