Merkel is yet to see action for Udinese this season.
"It was discussed in the summer, but then the boy decided to stay in Udine. But there is also the possibility that he will remain in Italy if he does move.
"Right now the player just has to find some self-confidence and then we will evaluate all of our options in January.
"The player is unhappy with the situation he finds himself in, but he needs to calmly work hard in an effort to convince the Coach.
"He is a boy with great potential who certainly wants a bit more space and he certainly needs to react to get that chance."
