Nani will be fighting for first-team spot at Manchester United this season as the competition for places becomes more intense.
"The competition is good," he said.
"It inspires you. If you have competition, you will train harder and push yourself in every game.
"At Manchester United, you have to be ready every time you go on the field."
The 24-year-old contributed nine goals and 18 assists - the highest in the league - to United's record 19th championship triumph but still recognises there is a challenge to remain a part of the first team plans.
"Of course I can get better," he said.
"That is what I am trying to do. It is not easy but it is what I look to achieve every year.
"If I can get more goals and more assists, that will be good for the team and help us in all the competitions we are going for."
