The Pole said: "It was one of the best games of the season. We played very well and scoring three goals on this field is very good. Very happy and content. If we play easier, we play better."
Asked what has changed after Xavi's resignation announcement, Lewandowski continued: ""The last two, three, four weeks we have changed the training a little, with more intensity. Physically, I also feel very good. My colleagues, the same. We want to take a step forward. This moment is very important.
"We want not only to win, but to play better.
"The most important thing is where we want to go. Let's see how we play in the Champions League against PSG. Our goal is to play like today. We have a team with a lot of potential. With young players, who play better and better, with more trust."
