Schalke defender Kyriakos Papadopoulos is frustrated by the contract stand off relating to teammates Lewis Holtby and Klaas-Jan Huntelaar.
Both players are off contract in June and on the shopping list of Arsenal boss Arsene Wenger.
"These issues overlap much publicly. As I said, it would be best if both decide quickly so we can all focus on our football," rapped Papadopoulos.
