Alisson told the club's website: "It will be a lot (of emotion) for sure.
"I (can) tell by myself these moments are not so easy to deal with; to say goodbyes. But everybody will be on that mood (and) really emotional. I think you get emotional when you realise how good was the spirit (and) how good was the journey.
"The gaffer gave the opportunity not only for the players to be part of this successful team, but he gave (that) to the supporters as well. He made the supporters feel part of that. I think that's why everybody will be so emotional."
He added: "Everybody here at the building at AXA (Training Centre) will feel his departure and all of his staff.
"But what this man made here (and) what he creates here is a legacy. Legacies last longer than trophies... he'll be eternal. He'll be amongst the eternal managers and eternal figures and eternal people of this club."
