Real Madrid say that gastroenteritis - not an anxiety attack - led to Thibaut Courtois' half-time substitution on Tuesday in the Champions League, reports BBC Sport.

The Belgian keeper was replaced by Alphonse Areola at the break with his side trailing 2-0 to Club Bruges at the Bernabeu - a game which ended 2-2.

Reports in the Spanish media claimed the 27 year old had an anxiety attack at half time.

In a statement released on Friday, Real said these claims are 'false'.

The former Chelsea stopper has instead been treated for acute gastroenteritis and is responding well to treatment, according to the Spanish club.
