During the press conference, Lopetegui tried to shift attention away from possible transfer targets.
Instead he tried to steer questions towards his sides's first La Liga game of the season against Real Madrid.
"Right now we're focusing on getting the best out of the squad we have which is a squad we love, we have a lot of talent and we're going to work with it," Lopetegui told the news conference.
"We like the players we have and I have no doubts about the squad I have. Our players have a fantastic attitude, and people are going to see a Madrid side with a lot of talent. The important players are the ones that are here, not the ones that are not."
Real Madrid have yet to sign a replacement for Cristiano Ronaldo, and have only brought in Alvaro Odriozola and Thibaut Courtois so far.
Some of Los Blancos important back-ups have also been loaned out with Theo Hernandez and Mateo Kovacic going to Real Sociedad and Chelsea respectively.
However, Lopetegui remains positive about his squad, and told reporters that the main thing on his mind was getting off to a strong start in the league.
"We have to focus on our games right now because the three points tomorrow are worth the same as all the other games, so we have to realise the season is starting now," he told reporters.
"I'm really impressed with the enthusiasm the players have to revindicate themselves and with the talent they have."
"We want to win this league title, it's the competition which examines your work every day. My biggest concern is to make sure we are capable of competing."
