The Germany international is looking to hit top form again against the English champions, and feels Jose Mourinho has every right to criticise his team in public
The Primera Division holders have won only one of their opening four league games, and are already lagging behind leaders Barcelona by eight points.
Khedira is not too worried just yet, though, and is hopeful that Madrid will find their rhythm once more against the Premier League champions.
"It's only normal that you lack a bit of confidence after a disappointing start to the season. Nevertheless, Tuesday's game against Manchester City is the perfect opportunity to get back on track," Khedira told reporters.
Jose Mourinho heavily criticised his team in the aftermath of their 1-0 defeat to Sevilla at the weekend, and the midfielder feels the Madrid coach was within his right sto do so, even though he disagrees with the Portuguese's comment that they are not yet a team.
"I think we’re a team," he added. "The coach has the responsibility, and we have the responsibility to play well. We have to play better to give the best of ourselves.
"The coach is right and we played a very poor game. He has every right to say what he wants before public opinion."
Madrid's match with City at the Santiago Bernabeu kicks off at 20:45CET.
