Anthony Modeste is in China ahead of a big-money move to CSL club Tianjin Quanjian. However, the French striker is unable to undergo a medical until the two clubs agree a fee.
The 29-year-old was expected to undergo his medical with the club on Tuesday, but this may be delayed due to Cologne stalling over their €35m offer.
Cologne’s sporting director Jörg Schmadtke told Express.de: “A medical check can only be completed if an agreement is reached.”
Modeste is expected to sign a 3.5 year deal worth €11m a year.
