The former Inter Milan midfielder is already catching the eye.
"He's feeling his way in, but you can see he's got quite a bit of skill there," Case told the Daily Echo.
"His fitness levels are probably not at their best at the moment, and he does not have a massive physique.
"But he is very gifted technically. Some of the balls he played through on Sunday (in the 3-2 win against Tottenham), some of them with the outside of his foot, were a joy to watch.
"He does look a decent player."
