The sheer sense of relief felt by the majority of Arsenal fans when the Gunners finally emphatically broke free from the shackles of their self-imposed frugality on transfer deadline day was evident for all to see.
With the £42.5 million capture of German star Mesut Ozil, long-serving manager Arsene Wenger secured arguably the best deal of the entire window.
With his breathtaking technique, vision and staggering array of passing, the former Real Madrid playmaker has - along with rejuvenated Welshman Aaron Ramsey - energised Wenger's midfield and provided an impressive catalyst for their recent excellent form.
Ozil's success during the early stages of his career at the Emirates Stadium has led many to suggest that Wenger will be sufficiently buoyed to lavish more eye-watering sums of money in order to bolster his squad for a sustained title bid in January.
With Arsenal's attacking unit - although led fantastically by formidable in-form Frenchman Olivier Giroud - somewhat lacking in depth, one man who has been persistently linked with a possible switch to North London is Spaniard Michu.
The Swansea star, who arrived at the Liberty Stadium from La Liga outfit Rayo Vallecano for just £2 million last summer, has been in stellar form for the Welsh club and was previously valued at £30 million by manager Michael Laudrup - an assessment that was endorsed by Swans chairman Huw Jenkins this week.
Now, while not wishing to understate Michu's qualities, at that sort of price, Arsenal should steer well clear of any potential deal.
Certainly, they should extend their new-found trend of paying substantial fees - but only if the player in question justifies that fee. Michu, who is not strictly a striker but nevertheless boasts an impressive goalscoring record, is a quality player with a canny knack of getting his name on the scoresheet but I think you would struggle to find anyone outside of South Wales who believes his ability is worthy of such a truly extravagant sum.
That is not to say, however, that Wenger should not bid for Michu. If he were to become available at a more modest price, then he would be a valuable addition to the Gunners attack either at providing adequate cover for Giroud ahead of Nicklas Bendtner and Yaya Sanogo or slotting in behind the lone frontman.
I fully believe Wenger should learn from the excellent signing of Ozil and continue to spend the apparently lavish sums he has at his disposal. However, the Gunners boss should remain shrewd and refuse to be held to ransom by such plainly extravagant and exaggerated fees.
Ultimately, despite his obvious talent, there are several better players available for £30 million than Michu and I suspect that a man of Wenger's class and experience probably knows that.
