Football transfers are highly intricate and complicated transactions which produce stories that live long in the memory. When a transfer is complete it's rarely the end of the narrative, and Manchester City's £38m deal to sign Sergio Aguero is no exception to the rule.

The Argentine has redefined the standards of centre-forward play in the Premier League and provided a moment of unprecedented hysteria that is unlikely to ever be emulated.

Given the impact he has made at the Etihad Stadium, it's almost impossible to escape the feeling that City may never have been the same side without him.

But a recent report from The Athletic suggests they may actually have John Terry to thank for giving them the advantage in their bid to lure the relentless goal machine to Manchester rather than London.

When City were still the new pretenders on the scene and vying to challenge Chelsea's supremacy both on the field and in the transfer market, Terry offered some advice about one of Europe's most promising talents at the time.

According to the report, Terry made it known to the club's powerbrokers that he wasn't convinced by Aguero's ability, particularly in regard to his movement, after playing against him in two Champions League fixtures.

The lynchpin's advice was not terminal for Chelsea's interest in Aguero, but it points towards a serious error of judgement that may ultimately have planted some seeds of doubt in Roman Abramovich's mind.

What is fascinating about the report is that Terry had completely misjudged the future prospects of a player who is so imperiously and consistently devastating that supporters have almost become desensitised to his brilliance; for most he merely reaches the astronomical height of the bar he has set for himself.

While Terry commands something resembling demi-god status in west London, this grave misinterpretation suggests that he is not omniscient after all.

It is the subtlety and intelligence of the 31-year-old's movement that has enabled him to score a whopping 244 goals for City, which either suggests he's significantly fine-tuned that facet of his game or Terry quite simply failed to recognise the enormity of the talent in front of him.

Aguero will forever be immortalised in the history books belonging to both the Premier League and Manchester City, but the course of time could have looked altogether different had the talismanic figurehead joined the Blues from the capital rather than Manchester.
