Munster captain Peter O'Mahony broke down as he tried to put into words what head coach Anthony Foley had meant to him.
O'Mahony was speaking at an emotional farewell to Foley, who died suddenly in the team hotel in Paris, just hours before his side were due to play Racing 92 in the European Champions Cup.
"You can't put that into words," O'Mahony said.
"The amount that we have lost now that he has gone is incredible - the rugby knowledge and brain, the man and the friend and coach and brother that we have lost. It's mad."
The remains of the 42-year-old head coach were brought to Thomond Park in Limerick for players and fans to say goodbye.
Older members of Foley's club, Shannon, formed a guard of honour as younger members looked on in silence.
As Foley's remains edged past the makeshift shrine on the gates of Thomond the hundreds who turned out to pay their respects burst into an impromptu song and applause.
Munster Rugby announced they will go ahead with their next game this weekend, against Glasgow Warriors, less than 24 hours after Foley's funeral.
Foley died from a build-up of fluid on his lungs as a result of heart disease.
