"I have done it for 20 years and it looked always like nothing. Suddenly, it becomes important so I'm quite pleased people realise that it is not as easy as it looks."
Arsene Wenger's reference to the difficultyof qualifying for the Champions League is poignant in the sense that for the first time in 20 years his team may not be playing in Europe's elite competition next season.
The Gunners have struggled in recent weeks,losing six and winning just three of their last 10 matches in all competitions to be knocked out of Europeand seemingly drop out of contention for a 21st straight top-four finish.
Wenger himself has been the centre of speculation regarding his own future, with an expiring contract at the end of the season expected to be renewed and an announcement forthcoming 'soon' - but right now the Frenchman says he is focused on the next game.
An impressive fightback against Manchester City in which the Gunners came back from a goal down twice seems unlikely to salvage Champions League football for next season and it's crucial that Wenger's side win the rest of their league fixtures if they are to finish in the top four come May.
Laurent Koscielny will undergo a test on his Achilles injury ahead of the game and it's currently unknown how long he'll be out for.
Wenger bemused by Alexis panic
The Frenchman's absence means the return of Brazilian centre back Gabriel to defence, although Wenger confirmed in his pre-match press conference that captain Per Mertesacker is fit and available for selection.
Santi Cazorla will miss the rest of the season after undergoing surgery on an ankle problem while Lucas Perez is still on the sidelines with a thigh injury.
Arsenal have no suspended players for this match.
