Arsenal skipper full of praise for Bastian Schweinsteiger.
The 23-year-old has, however, insisted that he is not scared of Joachim Loew's side, despite their eye-catching 4-1 and 4-0 wins over England and Argentina respectively.
"We have watched all of Germany's games. When you are here, you don't stop watching football and we know every team," he said.
"They are a very strong side, probably the strongest side in the tournament at the moment.
"As a team they are very quick on the counter-attack but defend very well.
"I like [Bastian] Schweinsteiger. He is playing really well. He is having a great World Cup.
"You never expect Argentina to lose 4-0 but in football today anyone can beat you."
Wednesday’s match is a repeat of the Euro 2008 final, which Spain won to claim their first major trophy since winning the same tournament in 1964, and the Arsenal midfielder is adamant he doesn't mind if the Germans possess the favorites tag this time around.
Fabregas added: "I don't mind if Germany are favorites. If they want to be favorites, we will accept that.
"We just want to play the game, we want to be a strong team, we want to beat them, and we want to reach the final.
"We are proud of what we have achieved so far but we want to go all the way.
"We are very excited about the semi-final. It is the first time in our history we have reached the World Cup semi-final so we will try to do well in it."
"Two years ago we played the European Championship final. We beat them, they could have beaten us.
"I don't think it is about mind games. These are two teams who have a very good relationship.
"I don't know if Germany had it with Argentina but I remember shaking all their hands at the end of the Euro final.
"We have a great relationship so I don't think there is going to be a problem."
Fabregas is facing a race to be fit for the semi-final, but is expected to take part.
