Liverpool assistant coach Vitor Matos says the new signings have quickly impressed.
Matos has commented on Darwin Nunez, Fabio Carvalho and Calvin Ramsay's first weeks with the club.
He told the club's website: "All of the new signings are top quality, so different positions, different profiles as well. Darwin is an aggressive player in terms of offensive and defensive – he's a proper No.9.
"Fabio is a player who can play between the lines and has a really good technical level, so he's a player who can play in different positions as well but he feels really comfortable between the lines.
"And Calvin didn't start training but we are really looking forward for him. So when we have new signings, it's always about how the team adapts to them and as well how they adapt to the team, so these relationships are quite important and that's why the pre-season is important as well. So it's good that we are working with them already now."
