Through the following official note, Real Madrid denied rumours having main goalie Thibaut Courtois suffering from pathological anxiety:
"In response to certain reports regarding our player Thibaut Courtois, Real Madrid wishes to express the following:
1. At no stage has our player been diagnosed with an alleged anxiety attack, and these reports are therefore completely false.
2. Thibaut Courtois has been diagnosed and treated for an acute case of gastroenteritis, with dehydration and electrolyte imbalance, which meant that he was unable to complete Tuesday night's game against Brugge.
3. The player is currently responding well to treatment".
