Granada defender Jesus Vallejo felt he wasn't treated fairly at Wolves last season.
Vallejo, then on-loan from Real Madrid, lasted only six months at Molineux.
He recalled to El Pais: "I trained like most, I took care of myself and I was prepared. But they didn't give me many explanations.
"There was something out there that I couldn't understand. I never knew and I will never know, no matter how much I ask.
"I prefer to focus on other things because it would be a waste of time. So I changed clubs to be surrounded by a healthier environment.
"Coming to Granada has been the best decision in recent times."
