The biggest question - to sell in January and earn at least a symbolic amount or wait until the end of the season and lose the player without receiving any sum. Clubs with players whose contracts expire next summer are considering such thoughts.
The very popular football website "Transfermarkt" has compiled a list of the best players whose contracts with their current clubs expire in the summer of 2018.
In the goalkeeper position - promising Athletic Bilbao player Kepa Arrizabalaga. However, the Basque is unlikely to wait for the end of his contract, as Real Madrid is expected to confirm the goalkeeper's acquisition this winter.
Four defenders make up the list - Yuafranas (Atletico), Stefan de Vrij (Lazio), Daley Blind (Man Utd) and a midfielder who can also play as a center-back Emre Can (Liverpool).
The trio of midfielders consists of well-known players - Mesut Ozil (Arsenal), Ander Herrera (Man Utd) and Leon Goretzka (Schalke). The future of the latter is also almost clear - the German should strengthen Bayern after his contract expires next summer.
Familiar faces are also in the attack - Alexis Sanchez, who could leave Arsenal this January, Juan Mata (Man Utd) and the famous Mario Balotelli (Nice) leading the line.
The player valued highest in this list is A. Sanchez - around 65 million euros. In second place is M. Ozil (50 million), and in third is L. Goretzka (40 million).
