Marseille coach Didier Deschamps has warned Arsenal the Champions League provides a welcome respite from domestic action.
The French side have struggled in Ligue 1 this term and are currently 15th, having won just one league game.
Yet, in Europe, their form could not have been more different, having recorded back-to-back victories against Olympiakos and Borussia Dortmund to currently lead Group F.
Backs to the wall
"Our bad start in the championship means we have our backs to the wall in every match, particularly at home," said Deschamps.
"But in the Champions League it's different. We have six points already, so there isn't the same pressure and the players can go for it a bit more and play without the same nervousness."
Arsenal, too, have suffered an indifferent start to the season and have struggled in the Premier League after the loss of key personnel over the summer.
Deschamps, however, still has the utmost respect for Arsene Wenger's team and believes they are still amongst the best on the continent.
"They're still a top European club and they qualify systematically for the Champions League," he added.
"They had a troubled summer, losing big players and bringing new ones in. I don't want to compare Arsenal today to their previous teams, but they still have 20 or so internationals.
"Their squad is full of quality. They've had problems in the Premier League but they're still a top team and they've played in this competition every season for a good while now."
