Karanka has described their preseason as "excellent".
"We have had an excellent pre-season and we hope to see continuity of this in each of the teams that our players go to. We've done the work that we wanted to do and the results are there. Let's hope that this week there are no mishaps and that on Thursday, when we all come together, we're in good shape to face the match against Valencia. It's going to be a demanding year right from day one," said Karanka.
