Real Madrid No2 Aitor Karanka admits they're delighted with the form of Sami Khedira.

The Germany midfielder is back to being a first-choice for coach Jose Mourinho.

"Sami has been in impressive form since his injury. He is a player who may go under the radar a bit, but we know how hard he works. It's nice to see how he plays, how he get into positions up front and how he picks up balls at the back. He is an important player for us," said Karanka.
