The 26-year-old has admitted the language is impeding his performance on the pitch since he finds it difficult to communicate with coach José Luis Mendilibar on the pitch
He said his main issue is with the Spanish language.
“When the coaches and the players speak I understand nothing. I always have to look at their face and actions in order to speculate what he is saying,” Annan revealed to pressmen in Spain.
“I am doing my best to get the Spanish language which to me is not easy. On the field I basically look at his signs and postures to get what he wants me to do.”
The midfielder who is originally owned by German Bundesliga side Schalke 04 always speaks through an interpreter during the club's meetings and press conferences.
Annan, who has previously played for Norwegian sides IK Start and Rosenborg BK as well as Vitesse Arnheim in Netherlands has been instrumental for the club since joining them this summer.
