As frustrating as Arsene Wenger can be in the transfer window, there is no doubting his ability to sense a good opportunity.
The pursuit of Mesut Ozil from Real Madrid was executed brilliantly by the French tactician. Wenger waited and waited for the right time to move in the transfer window before finally sealing that all-important marquee signing on deadline day.
Amidst growing criticism, Wenger moved late, leaving their Premier League rivals shocked with no time to respond.
Similarly, the signing on Mathieu Flamini from AC Milan is likely to benefit the team greatly. It's the second time Wenger has signed the tireless midfielder on a free transfer and an impressive display against Tottenham gave fans a sense of optimism.
Spending millions looks good in the papers, as Tottenham realised, but there is no reason why Flamini can not be an excellent acquisition and Wenger must be credited for sensing the opportunity.
That knack for moving at the right time for a player seems to be in action again after Arsenal were linked with Barcelona's reserve right-back Martin Montoya.
The 22-year-old has been linked with a move to Arsenal and Liverpool this week after his agent revealed Barcelona are yet to offer his client a new contract.
With Montoya's current deal expiring next summer, Wenger can begin discussions with him as early as January, with a view of bringing him to the Emirates on a free transfer.
Such an addition would be fantastic for the squad.
Arsenal are in dire need of some defensive reinforcements. The constantly injured Thomas Vermaelen is leaving the squad with just two recognised centre-backs in Per Mertesacker and Laurent Koscielny.
As a result, Bacary Sagna has been drafted in to a central position when required. With Sagna impressing at centre-back, he can become a permanent third choice option or fourth choice when Vermaelen returns.
That leaves Carl Jenkinson as the lone right-back in the first team. Although the young England player regularly shows promise, he can't be expected to play 50 games a season at the tender age of 21.
Montoya has endured a difficult time at the Nou Camp. An impasse to the first team, in the form of Dani Alves, shows no signs of moving any time soon.
In a brief spell under Tito Vilanova last season, Montoya got his chance when Alves was injured. He duly impressed but could not keep his place when the Brazilian returned to fitness.
The Spaniard is at a critical age in his development and needs first team football. His exclusion from the match day squad this season echoes similar misuses of youth prospects at Barcelona.
Thiago Alcantara finally snapped after finding his opportunities limited despite impressing every time he was given the chance to. He left of Bayern Munich in the summer and now Montoya should follow him out the exit door.
With excellent technical ability, Montoya suits Arsenal's style and would fit seamlessly in to a system that relies on the full-backs contributing to attacks.
Wenger can offer Montoya plenty of playing time - at least much more than he is currently getting.
With the vultures at Anfield seemingly already swirling, the Arsenal boss shouldn't hang around to sign this talented young player.
