Juventus defender Leonardo Bonucci admits Franz Beckenbauer has given them extra motivation for the second-leg of their Champions League tie with Bayern Munich.

Beckenbauer branded Bonucci's teammate Gigi Buffon a "pensioner" after Bayern's 2-0 win.

"We have respect for his words, but this will fire up both us and Gigi. We want to go through to the semi-finals," said Bonucci.

"It's still wide open and we will put 110 per cent on to the field. That's not to say we'll start off pouring forward without thinking about the consequences, as there are 90 minutes to score a goal."
