Bayer Leverkusen star Hon Seung-min insists the German side will be primed to take on Paris Saint-Germain next week.
Die Werkself take on the French giants in the first leg of the Champions League Round of 16 on Tuesday, February 18 and South Korean winger Son is confident the Budnesliga outfit will put in a good shift.
"We've got a few tough weeks coming up," Son said.
"We'll be prepared for them (PSG) but obviously, that's a matter of a lot more hard work."
