Just consider how Sahin feels now:
His trainer critizes him in open public via press, although Sahin did not even make a mistake.
After a long injury he waits to be integrated into the squad.
His national-trainer says, that Sahin is 100% fit. But Mourinho makes controversial statements about Sahin's national-team and indicates that Sahin's matches for Turkey don't really count for Mourinho. No disrespect to Mardid's other Midfield players, but players like Granero or Diarra (no matter how well they play) don't have the football-intelligence and the class which Nuri has.
He's now fit again for 4 months, and in 2012 he didn't even play a single minute.
I don't think, that there will be any loan-transfer to Valencia or another team.
A player who turns down transfer-offer from a giant like Bayern München doesn't get loaned to a second-rate Spanish team.

If a Coentra costs 30 Million €, a Sahin would cost even more on open-market.
But he had a buy-out clause for the absolute Top-Teams (ManU, Real etc) for 10 Million €.
When Sahin signed that contract with Dortmund, Dortmund was in lower-level of Bundesliga fighting with serious financial-problems (debt).
It was not clear whether Dortmund can make a comeback to Bundesliga's top-ranks.
Watzke (Dortmund pre4sident) and Michael Zorc (Sports Director) said, that without the buy-out clause Nuri wouldn't have renewed his contract at Dortmund.
Years passed, and now Dortmund (with 4th highest stadium-attendance in Europe) is slowly recovering from nearly-bankrupty again and becoming a big team with several good players and talents.
Sahin had big impact last year making Dortmund Bundeliga-Champion.
It seems Dortmund will be Champion this year also.
Plus, Dortmund and Bayern made transfer-bidding for Germany's new shooting star Marco Reus (already called by Löw into national-team) who plays for Mönchengladbach, but comes from Dortmund Youth. Dortmund won the battle against Bayern for 17 Million €.
Sahin could've played Bundeliga and Champions-League with Dortmund this season.
He could've developed and gained more experience.
Instead Madrid treats him like shit.
In Summer Sahin will hopefully leave, and in next match you'll play against him he'll hopefully make Vendetta with you. You deserve it for trying to destroy his career.
