The January window is not all about who can sign whom for the price of a small country.
Yes, Liverpool have already broken the record price for a defender when they signed Virgil Van Dijk from Southampton. And Barcelona have smashed their own record for a player with the just-about-done acquirement of Philippe Coutinho from Anfield.
But the most shrewd pieces of business often fly under the radar.
Chelsea have been all like an astute browser at Dubai Shopping Festival and may have got the steal of the January sales in the shape of Ross Barkley.
The £15 million they handed over to Everton for the Englishman is paltry compared to some of the deals going on and the midfielder himself called his five-and-a-half-year deal with last season's Premier League champions as “unbelievable”.
OK, he has been out injured for seven months with a hamstring injury, but he will prove why he is one of the best in the game.
I still cannot believe the powers at Goodison Park let him go at that price.
"He's very young and has a lot of space for improvement," said Chelsea manager Antonio Conte. "We must have patience to help him recover."
Recover he will, and flourish in the blue of Chelsea.
Now we wander into the realm of the slightly more unknown.
The early rival to Barkley for snip of the sales season is Cenk Tosun from Besiktas to Everton.
The Turkey international agreed a four-and-a-half-year contract and has helped the Turkish side reach the last 16 of the Champions League, and has scored in almost every other games during 96 outings for Besiktas.
With an over-reliance on the ageing Wayne Rooney and manager Sam Allardyce’s eye for a good bargain, he could be just what the doctor ordered for Everton and any struggling Fantasy Football manager.
So who next?
If Brighton get a hold of Moussa Dembele – no not that one, the other one with the double ‘s’ – it could prove vital to their Premier League survival.
This lad plays for fun up front for Scottish champions Celtic and could be £18 million well spent if he can grab the goals needed to keep Brighton out of the relegation dogfight – they are only four points above the drop zone.
That outlay will then seem like a pittance compared to the silly money a team gets for playing in the Premier League.
So keep an eye on those small deals as they often prove to be the literal game-changers.
