Serb Jovanovic signed on a free in the summer but is not happy
at being a bit-part player.
He said: "I am starting to find the time dragging on.
"I'm a fighter but if things do not sort themselves out I will
change club - even though it is too soon to think about it yet.
"I'm on form, I'm working hard and I have started eight
competitive games.
"But I've not been in the starting XI for the last few matches -
and I've not even come on as a sub."
The former Standard Liege forward, 29, added; "I have to adapt
to a new system over here. I have to defend all the time.
"Just three or four teams in the Premier league play attractive
football. The others set great store by commitment, discipline and
defending.
"I miss Standard and the city of Liege."
