With 12 days left of the transfer window, the speculation is likely to go from full throttle into overdrive. In fact, it has done just that with this latest story.
According to Spanish newspaper AS, Chelsea launched an incredible offer worth €55million (£39m) for AS Monaco's rising star Anthony Martial.
But that isn't even the most surprising aspect of the story. The Ligue 1 club, who are dramatically attempting to curb their spending after several seasons of heavy investment, rejected it.

There is so many aspects to this story that seem ludicrous, but one that is in doubt is Martial's incredible potential.
The 19-year-old broke into the first-team under Leonardo Jardim last season, benefitting from Radamel Falcao's departure to the Premier League. He scored nine goals in Ligue 1 and three more in France's cup competitions.
Of all the Under-21 strikers in Europe, only Domenico Berardi of Serie A outfit Sassuolo scored more. And the Italian recently turned 21, meaning Martial has two years to catch up.
The Mail seem to have a more sensible view on matters (Never thought I would say that). They report that Chelsea's technical director Michael Emanelo watched Valencia beat Monaco last night.
One of his main duties was to keep an eye on Martial, although it is also reported that he was just keeping an eye of Chelsea's potential Champions League opponents.
