Tottenham boss Ange Postecoglou admits they have to be clever in the January market.
The North London club had not planned on being prolific buyers in the winter, but their needs have changed.
Injuries, especially in central defence, are causing an issue for Postecoglou at present.
Asked about January, he told reporters: I guess the challenge for us was they all came at once as it hasn't been staggered.
In terms of January, the planning is well away with that. Johan has come in and he's leading that in terms of all the background work.
My involvement and my own sort of ramp up to it as we get closer to January and understanding exactly what our requirements are at the moment, although work has been done in the background with Johan leading it and he's brought in some people to help him in that area. We'll work with him when the time is right."
