Despite defeating Tottenham Hotspur by a slender 1-0 margin by virtue of a swift Olivier Giroud first-half strike on Sunday, Arsene Wenger still admired the quality acquired by Arsenal's local rivals throughout the summer.
However, the Frenchman believes that, because it takes time for transfer window purchases to acclimatise to their new surroundings, Andre Villas-Boas' recruits will only improve later in the season.
'You need a bit of time when you buy many players, that is normal,' Wenger said, as quoted by the club's official website. 'But the players they have bought are quality, you could see that. You always need a bit more time when you are buying more than three players.'
Tottenham have embarked on an aggressive assault on the summer market having bought Paulinho, Nacer Chadli, Roberto Soldado and Etienne Capoue, while adding Vlad Chiriches, Erik Lamela and Christian Eriksen last Friday.
Of the £105.7m worth of talent signed, four players featured in the North London derby with Soldado coming close to making a significant impact with a penalty appeal after the half-time break.
Tottenham enjoyed the lion's share of possession, a rare feat for a visiting team at Arsenal's Emirates Stadium, but they lacked the Gunners' incisiveness and pace. And, even though Wenger et al collected maximum points, it should not detract away from their threadbare squad.
Wenger may point to how it takes time for new players to settle, but he has had the entire summer to make the signings necessary to push Arsenal on from a side challenging for fourth, to one that could challenge for first.
Instead, he has a nervous day ahead in order to exchange terms with a hat-trick of players in order to beat the deadline of 23:00 BST.
'I am ready to pay what we can afford, even if it is a bit over the market [value] and as long as it is not crazy,' he insisted. 'Maybe something will happen in the last 24 hours, maybe not.
'I want to add super quality to our squad. We need one or two super players and we will try to add that. We have 24 more hours, so maybe we can surprise you. Maybe not - but I am confident.'
Arsenal have been linked with late moves for Mesut Ozil, Angel di Maria, Julian Draxler, Demba Ba and Abel Hernandez.
