The Germany international confessed that the Gunners rode their luck to some extent and were guilty of switching off against Crystal Palace.
Arsenal edged a London derby against Crystal Palace at Selhurst Park yesterday, weathering a late storm from the hosts to record a much-needed 2-1 victory.
After Santi Cazorla and Olivier Giroud had given the Gunners a 2-0 advantage, Alan Pardew’s men rallied and scored late-on throughout Glenn Murray.
With the home side also hitting the post in the dying minutes of the game, Arsenal will be glad to take all three points, which moves the North London club up to third place on the Premier League table.
Per Mertesacker has spoken out about his team’s win and admitted that the Gunners were lucky not to be pegged back in the latter stages.
“At the end they tried to put us some pressure and get some strikers on,” the German centre-half told the club’s official website.
“They nearly scored the equaliser so we were a bit lucky at the end. Overall, we are absolutely delighted with the three points and we move on.
“They have pace up front and good headers of the ball too. They nearly scored in the first half and at the end they had quite a few chances.
“Sometimes you lose games, especially at the end. We were lucky today but that was a bit of a warning for us not to switch off too early.
“As I said, I’m absolutely delighted to take the three points.”
Since losing the North London derby to Tottenham at White Hart Lane, Arsenal have put together a string of positive results and will now look to hold onto a top four place for the rest of the campaign.
Mertesacker and his side face Monaco in the Champions League knockout rounds this week and will be pleased to have recorded victory over Palace as a pre-game confidence booster.
