Speaking to the media, FIFPro Europe president David Terrier said: "FIFA refuses to listen and engage with the players, the main labour resource of our industry, who are there on the pitch, creating a powerhouse of European and global entertainment culture, and pushing their bodies to the limit.
"But we have listened to our players, have received the same messages for a long period of time, that they are playing too much and do not have enough time to recover. Ahead of the worst season ever for workload, many have also decided to talk in public with the same message: enough is enough."
