Swiss therapist Mattia Piffaretti will be available to the 12 main tournament referees during the tournament that begins on Saturday. The service is not obligatory.
Germany's referee in the Euro 2008, Herbert Fandel, said he welcomes the addition, but won't need a shrink.
“I don't need him,” Fandel told news agency DPA. “In my career I've lived through so many situations that help me get through difficult phases.”
