Much of the talk this transfer window will be about Arsene Wenger signing a new striker.
Occasionally attention will turn to the contract situation of right-back Bacary Sagna.
However, both Wenger and Gooners should be concerning themselves with another matter - the impending expiration of Tomas Rosicky's contract.
Signed for around £7million in 2006 to replace the departing Robert Pires, the energetic midfielder was an instant hit with the Arsenal crowed.
A midfield live-wire capable of beating men, playing the final pass and unleashing the odd thunderbolt, Rosicky formed a formiddable quartet with off-field pals Cesc Fabregas, Alex Hleb and Mathieu Flamini.
However, an injury - and subsequent series of setbacks - saw Rosicky sitting on the sidelines for almost two seasons.
When the player dubbed 'Little Mozart' returned, he struggled to find the form that once saw him lauded as one of Europe's top playmakers.
Many Arsenal fans called for the attacker to be moved on, especially when he continued to pick up niggling injuries.
Yet a resurgent Rosicky was a man on a mission.
As Arsenal trailed Tottenham by a mammoth 12 points towards the back end of the 2011/2012 campaign, Rosicky's form went a long way to inspiring their incredible comeback.
The Czech even netted and turned in a man of the match performance in their 5-2 win over Spurs that season.
And ever since, Rosicky has proved to be Wenger's Mr. Reliable.
Rosicky though now 33, still has plenty left in his legs.
His energy embarrassed his younger Spurs counterparts during their FA Cup tie.
Rosicky has plenty more to offer Arsenal, and Wenger would be foolish not to recognise this.
