"I have played the three best leagues in the world and I have enjoyed them all," Joselu told reporters on Thursday.
"It is true that La Liga adapts a lot to my game. In the end, age is just a number.
"About the rumours [to Real Madrid], now I want to focus here, we'll talk when the stay is over. Starting Monday. Let's see what happens.
"Yesterday was a very nice day," the striker added.
Joselu came off the bench to score the winner for Spain in their Nations League semi-final against Italy.
According to Fabrizio Romano, Real Madrid are now finalizing details to complete the signing of Joselu from Espanyol.
Los Blancos want the striker on loan but Espanyol are said to be working towards including a mandatory buy option.
The 33-year-old Spanish striker will become the first striker brought in to replace Karim Benzema.
