Silva said: "I don't think in this situation. It is not something that is ever in my mind because when I'm winning five or six games I'm not thinking if I win I will renew the contract and get three years more.
"It is something that doesn't stay in my mind. A football manager doesn't have to lose one second to even think in this situation.
"We have to go with 'we worked well during the week, we have planned everything well, tomorrow our players they will perform well playing in our stadium and we have to show togetherness to win a football match."
Silva added: "We have to play with heart, we have to play with the atmosphere in our stadium but we also have to be patient. It is in our mind to win the match, be calm when we have to be and showing the desire to win the game."
