This might actually come as news to Liverpool Football Club, but you can extend contracts outside of the transfer window.
Following a summer in which the Reds' off-pitch efforts have largely been focused on retaining existing players rather than buying new ones, several of the club's biggest names are now weighed in. With some notable exceptions.
The fate of the famed front three is still up for debate, but of those three the only noise around a new deal has been surrounding Mohamed Salah.
And the noises haven't always been promising.
With Salah's agent Ramy Abbas Issa clearly a fan of sending tweets that live up to that often overused term 'cryptic', the dance surrounding a potential new deal for the Egyptian has been ongoing for some time, with the music showing no signs of stopping.
There was Issa's full stop - that was it, a full stop - when Salah was substituted in the home defeat to Chelsea last March, while at the start of this season there was "I hope they're watching" after his client scored against Norwich. Of course they were, just as they were last December when Salah dropped some not-so-subtle hints to the Spanish press.
Yet with the forward surely aware that Barcelona and Real Madrid are pretty much closed options for the world elite these days, it was obvious that those flirtations were merely designed at getting Liverpool to the table rather than any outright transfer interest. The same can be said for Issa's tweets.
It would be easy to label the situation as an 'impasse' as one of the finest footballers in the world plays into the penultimate year of his contract, but Liverpool will doubtless have wanted to make Salah's contract one of their final extensions simply because it will be the costliest.
If Virgil van Dijk knows Salah is getting X a week, then will he ask for Y?
For the rest of us, putting any precise figure on the deal is likely to be a fairly fruitless exercise given that Liverpool's contracts operate on a largely incentivised bonus structure, something that would have kicked in at the end of last season when the Reds scrambled to qualify for the Champions League.
Salah and Issa will have a figure in mind for a basic salary, but both will be aware that so much can depend on what the forward achieves at the club.
That is the arrangement that has taken him to the heights he's reached, and it doesn't look like changing.
For now Liverpool just want Salah to keep playing and keep delivering the type of displays he so often has done, with Salah still wanting the club to provide him with the stage upon which he can shine.
Both seem happy with that arrangement at the moment. It is working for them and they are working for each other.
Bringing that spirit to the negotiating table is the next goal.
