The Spaniard’s team take a slender 1-0 lead into their return quarter-final next week, following Arturo Vidal’s goal 109 seconds into Tuesday’s first-leg tie.

And Guardiola, who is still seeking his first Champions League as Bayern boss in his final season at the Allianz Arena, is confident the Bundesliga side have what it takes to reach the last four.

“In the second leg, it is the difference-maker,” the 45-year-old said.

“We will go to Lisbon, watch the first-leg again and be prepared. We are now in a better position before the game.”
