If Real Madrid want some top-class reinforcements then they have to move fast.
Like neighbours Atletico, they can kiss goodbye to any transfers for the next 18 months if they don't make any purchases or indeed authorise any sales before the end of the month.
An appeal against a recently imposed FIFA transfer ban is almost certain to fail and time is very much of the essence.

Whether Zinedine Zidane has any immediate targets is unclear but if there's a chance for Florentino Perez to wave his "Galactico" banner one more time, rest assured Real's president will grab the chance with both hands.
Let's take a look at three transfers that may happen before the end of January...
The Polish centre-forward has been the chief destroyer of Real's European dreams in recent times, scoring four goals for Borussia Dortmund back in the 2013 Champions League semi-finals to send Los Blancos packing.
A move to Bayern Munich has only enhanced his striking excellence and a five-goal blast in a nine-minute spell against Wolfsburg earlier in the season is a record that will probably never be beaten
He is the consummate centre-forward and it's no wonder Real are trying to sign him.
Even Bayern's Franz Beckenbauer has admitted it, paving the way for the deal to be concluded.Der Kaiser told DPA via Nicholas Godden of the Daily Mail: "Robert Lewandowski has been mentioned as a possible candidate for Real Madrid."
He certainly won't come cheaply but if the financials can be agreed, there's no reason why this one shouldn't happen.
James Rodriguez to Manchester United
It's no secret that both Perez and Zidane are becoming exasperated with the antics of James Rodriguez.
Late night partying, speeding at 200mph, overweight. The charge sheet is extensive.
As Barcelona showed almost a decade ago with Ronaldinho, it doesn't matter how big the name and how good the talent, no one player is bigger than the club.
According to El Confidencial via Telegraph Sport, Louis van Gaal is readying a £60m bid to test the waters and given Rodriguez's current malaise, Real would be mad not to accept it.
Manchester United have long wanted a marquee signing to take their club to the next level. With no real possibility of Cristiano Ronaldo, Gareth Bale or Neymar making the move there, Rodriguez is the next best option.
It would take the sting out of any Lewandowski purchase too.
One of European football's hottest properties, FC Schalke's Leroy Sane is on Real's radar.
According to Marca, both Manchester City and Barcelona have shown a keen interest in the 20-year-old and whilst Real may have preferred to make a bid in the summer, the ban is forcing their hand.
At €39 million, Sane doesn't come cheap but the Germans won't let him go for a penny less than his buyout clause and Real don't have time to negotiate.
