The defender is off contract in June.
Clarke said: â€śI have given thought to it. Itâ€™s an ongoing situation. I said earlier in the week that the last six games wonâ€™t change the situation for any player at the club.
â€śI am comfortable in my own mind where Iâ€™m going but we wonâ€™t make that decision until the end of the season and nobody will know until then. I havenâ€™t sat down or had long conversations with him but I know Goran is happy here.
â€śHe is happy with the work that he gets and the only thing heâ€™s unhappy about is that he hasnâ€™t had more minutes on the pitch. He was in the team but he lost it due to an unfortunate incident.â€ť
Clarke continued: â€śIâ€™m happy with him. Heâ€™s done well and been a good addition to the squad.
â€śBut I donâ€™t socialise with him so I donâ€™t know how he well he has settled in but I see him day in, day out, and he seems comfortable. The boys like him, heâ€™s a good character and he seems comfortable in England.
â€śWe will sit down and have that final conversation around the end of the season.â€ť
