Vicente del Bosque, Spain coach
[Diego Costa] is truly giving his all; he wishes to pay us back for all the support we gave him. He feels comfortable with this group of players and we appreciate his efforts and the way he makes himself available on the pitch. He combined well with Paco Alcácer, who needed to find space.

During the half-time break, I told him to stay focused because if he kept calm he would get a lot of satisfaction. We noticed he was upset with his performance. He was getting frustrated because he couldn't finish, but when a player puts in as much enthusiasm as he did today, he eventually gets what he desires.

[On Iker Casillas and David de Gea] I would not like to make a difference between them and the rest of the team. We knew we were going to make some changes and we wanted to have a smooth transition in the goalkeeping position. That means that Iker will facilitate and David will start fitting into the team slowly, as long as both play regularly for their clubs.

We would like to be more complete in our style of play and in the second half we lacked intensity. We would have liked to keep more possession and look for more space and openings. They were pressing us very high and put a man on Sergio Busquets, who had to step back to get the ball and create a numeric advantage for us. We pushed our full-back on and we accomplished our game plan. We tried to create some dangerous situations between their lines with David Silva and Andrés Iniesta.

Luc Holtz, Luxembourg coach
To play against such a technical opponent is hard for any team. I am very satisfied with our EURO qualifiers, but I did not like Thursday's [3-2 loss to FYR Macedonia] because we could have achieved a much better result. What we missed is a bit of determination.

[Mario] Mutsch has experience and even though it was not his best match, he is important for us. Christopher Martins was substituted because he was tired and I thought it was the best thing to do for the team. He played a great game on Thursday and we have to remember that he is 17.
