"So we had some statistics, we were well prepared, that Kepa is the best in percentage in saving penalties.
"The analysis guys and the goalkeeping coaches showed me, introduced me to the data, then we spoke with the players, that this can happen when we play in a knockout game, and since then they know.
"It's fantastic how Eddy accepts it. It's fantastic how this talk went before the cup game in Barnsley. Since then they know.
"Of course we needed to do what's good for the team. It was necessary. I'm happy that it worked.
"There is proof that Kepa is better at this discipline. These guys are true team players. I am happy for Kepa and happy for Eddy, to have a goalkeeper like this, to not show the pride to not step off the field, and is happy to do it for the team, to take one for the team. It's top."
