A quick note on injuries - generally good news. As mentioned before, Nihat is out for a month, until about mid-February. The doctors do not want to risk reaggravating his knee, so they are making him take an entire four weeks off.
Gonzalo's injury is strictly a meniscus issue. He is expected to be back for the weekend's match. If he isn't, it will be Fuentes and Cygan in central defense, with presumably Edmilson as the backup. That is a bit scary, even against Osasuna.
And Angel should not miss any time, but he will be in a splint for four or five weeks. It should not affect his ability to practice or play, so he and Javi Venta will be back to battling for the starting right back spot.
