Wolfsburg coach Dieter Hecking says he expects his side to face a backlash at Real Madrid in Tuesday's Champions League quarter-final return match after the Germans' stunning 2-0 first-leg victory.

"If it was the case that Real had underestimated us in the first leg, they definitely won't do that again," said Hecking.

"We did a good job of selling ourselves well in the first leg, but we are going to have to give everything we have in order to pull off a huge sensation."

Real have a huge job on their hands at the Santiago Bernabeu if they are to go through to a sixth consecutive Champions League semi-final after succumbing to a Ricardo Rodriguez penalty and a Maximilian Arnold goal.

Wolfsburg suffered something of a Champions League hangover on Saturday as they were held to a 1-1 draw in the Bundesliga at home to Mainz, although Hecking rested four of the side which beat Real.

However, last season's German Cup winners, who are in the Champions League knockout stages for the first time, have tended to struggle immediately after European games this season, picking up just 10 league points from a possible 27.

Germany forward Andre Schuerrle says the team is "one million percent ready" for Tuesday's return leg although he expects Wolfsburg will have to run themselves into the ground to reach the semi-finals.

"It's going to be an intensive game," said Schuerrle.

"We'll have to play like we did in the first leg or maybe even better.

"We'll need to be mentally switched on from the very first minute.

"We have already shown that we have the quality up front and if we get a goal, that will make it all a lot easier."
