Nothing of better value (not saying King is of value) ever comes on January window.
Not necessarily true. VVD, Suarez, Vidic, Evra, Bruno Fernandes, Bergwyn, Haaland, Djeko, Doucoure, Ndidi, Matic, Aubemayang all moved to bigger clubs in January. Loads more as well.
Can be harder to get value, but as long as it's not a panic buy, and it's planned and strategic, you can get good players in January.
