He said: "Josemi can be an important player for us. He is a good player, an aggressive player, and he is getting more used to English football now.
"He played very well at centre back last week. I knew he could play there because he spent a year in that position with Malaga. Of course he can also play on the right of the defence as well so he gives us different possibilities.
"He was unfortunate last season because he had so many injury problems, but if he can stay fit then he will be an important member of our squad this year."
