Barcelona chief Deco praised new arrivals Joao Cancelo and Joao Felix.
Manchester City fullback Cancelo and Atletico Madrid attacker Felix have joined Barca on-loan.
Deco said of Cancelo: "He has a lot of experience, he is a mature player who knows the moments of the games and how to manage them.
"He is a player who brings competitiveness, quality, we always play with Araujo, Kound and we needed to have a player in this position (right-back)."
Deco also said: "The players wanted to come and they understand the role, that we need their help and they did it.
"Joao Cancelo and Flix follow this example, also our captain, Ter Stegen, who has renewed, helping in Fair Play, and giving stability. It's important to have players with this spirit, and thanks to their efforts the signings have arrived."
