Even with the buyout clause, I can't see Sahin wanting to stay, since he has said he wants to make it at Madrid recently. He worked hard for Dortmund to earn his move to Real, why would he get there then throw it all away after one season? Still, the buyout clause isn't confirmed by all sources just yet.
I considered it a good deal back when it was a 1-2 million pound fee with a lower buyout clause as well as paying less of his wages. Also didn't hear that he really wants to make it at Madrid.
Regardless, he would be a cut above any of your current midfielders, but after spending so long out, I can't see him coming back to the top class levels he was hitting with Dortmund after a while. Would've been fine if it was with the view of a more permanent deal, but as a loan, not fine.
Signing of the season is way overboard, definitely Liverpool's best signing, but there have been at least ten better deals this season in terms of both value for money and the talent of the players brought in.
