Speaking to reporters, the 39-year-old said: "I'm really focused on seeing my players, to understand my players and I think that is one of the problems of the club. We have to focus on what we have, we have to focus on the academy and also to have clear profiles of the players when you get them. It's a lot of details you have to manage.
"You can see set-pieces, sometimes you look at our team, we are a small team compared to the others. Every detail counts and you have to very clear, first in the profiles, arrange all the process and then go to that phase of buying and selling players."
He added: "We have international players, they are good players and we need time to teach our idea and then we will see. Because this is a massive club. If you don't win, the coach goes, the players go. We have to improve as a team, we have to arrange a lot of things in our club before thinking about just buying or selling players. There's a lot to do, so let's focus on improving our players."
