Los Blancos appear to have refound their best form in La Liga and the Champions League, after a busy month in which they beat Barcelona twice, and Manchester United over two legs in Europe.
Khedira told Marca: “If you aren't a team you can't beat Barcelona in two consecutive games and knock Manchester United out of the Champions League. Now I can say that Real Madrid is a real team once again.
"It's difficult to say what happened. We started really badly, very slowly. However, at the beginning of this year we started remembering what we're good at, playing like a true team and not hanging our heads when we concede goals.”
The 25-year-old arrived at the Santiago Bernabeu in 2010, with Jose Mourinho securing his signature on the back of an impressive World Cup, and Khedira revealed his admiration for the Portuguese.
He continued: "I’m really happy as one of Mourinho's players and I feel very much at home at Real Madrid. Mourinho was a great choice by Real Madrid, fantastic for the club. He’s an outstanding coach and a great person. If it were my decision, Mou would stay. I want him to stay."
Madrid were paired with Galatasaray in the quarter-finals of the Champions League in last Friday's draw and the Germany international already has his eyes set on an all-Spanish final at Wembley in May.
"We all really want to win it. Real Madrid–Barça is the biggest game in the world and everyone would be pleased if that were the final at Wembley."
