“Our fans will always demand the best from us and this is a good thing for us. In the same way they support us always, and we have to be ready to play football, to defend and attack well, to be a strong and solid team. To be able to beat them there is not going to be easy, but this is our aim, always.”

“Tottenham are a very compact, very narrow team, very aggressive and we have to be able to beat this kind of team.
“They do a lot of very good things, but I prefer to put the focus on what we have to do. For me that is more important.
“We will try to use our decisions too. We will try to beat this kind of situation playing well, understanding each moment and playing out of mini-matches well.
“Tottenham is a team that has a lot of big intensity always and we have to be ready to have the right answers, but I won’t talk about tactics here!”
