Liverpool boss Arne Slot says his players should be themselves and follow their emotions as they come to terms with the death of team-mate Diogo Jota.
Portugal forward Jota and his brother Andre Silva died in a car crash on 3 July in the Spanish province of Zamora.
The Reds play their first pre-season friendly since Jota's death at Preston North End at 15:00 BST on Sunday.
In his first interview since Jota's death, Slot told Liverpool TV: "If we want to laugh, we laugh; if we want to cry, we're going to cry.
"If they want to train they can train, if they don't want to train they can not train. But be yourself, don't think you have to be different than your emotions tell you.
"We will always carry him with us in our hearts, in our thoughts, wherever we go."
The funeral of the brothers took place in their hometown of Gondomar last Saturday when a large Liverpool delegation, including Slot, were in attendance.
There have also been floral tributes at Anfield, where Jota's wife Rute Cardoso, members of the brothers' family and Liverpool's squad all visited on Friday to pay their respects.
