Goalkeeper Simon Mignolet has said that the defence was not to blame after Liverpool nearly let a three-goal lead slip in their 4-3 win over Arsenal on Sunday.

Jurgen Klopp's side went 4-1 up over the Gunners in the second half at Emirates Stadium in their opening game of the Premier League before the hosts hit back to set up a nervy finish.

Manager Jurgen Klopp took some responsibility for the scare following the game as he felt he over-celebrated Sadio Mane's fourth goal and gave off the message to his players that the three points were secured despite there being plenty of time left to play.

However, Mignolet believes the Reds were good defensively on the day, but did admit that there are "lessons to learn."

"I don't think it was our mistakes which led to the goals being conceded," Mignolet told the Liverpool Echo. "I thought we defended really well, just like we did against Barcelona at Wembley.

"For the first goal we were a bit under the cosh and the second goal was unfortunate -- a deflection we couldn't have done anything about.

"The third goal was a set-piece where they took the free kick early and we weren't quite organised.

"When we made it 4-1 we needed to make sure we didn't concede but one goal can change a game. That's what happened with the deflection.

"The crowd got behind them again and they got a boost from that. But we kept our heads and got back to playing at the level we were at in the opening 20 minutes of the second half.

"Keeping the ball like that takes the pressure away from us. That's what we need to be doing throughout the 90 minutes."

The Belgian shot-stopper saved a Theo Walcott penalty in the first half just when Arsene Wenger's side were firmly on top in the affair.

"I was pleased with the penalty save," Mignolet added. "We had studied where Arsenal players put their penalties but it was difficult because their normal penalty takers weren't on the pitch. It happened to be Walcott and luckily I picked the right spot.

"There are a lot of things we can learn from this game but it's great to start with a victory, especially with it coming at the Emirates, a ground where we haven't taken many points in the last few years.

"As a team we have lots of attacking options now. A lot of players with pace who can make the difference going forward.

"The second half at Arsenal was like how we played against Barcelona. We can build on this."
