Rudi Skacel's agent has denied that his charge has already penned a permanent deal with Hearts.
The Czech winger has been a sensational addition to the Hearts squad this term and he has chipped in with 16 league goals from just 31 starts.
His loan spell from Marseille is due to expire next month and reports from Scotland suggested that a permanent deal was already in place.
However, Pavel Zika insists that no such agreement is in place - although he would not rule out a permanent deal.
"There are still more clubs interested," he told CTK.
"On the other hand I see no problem if he stays at Hearts because he became the fans´ favourite."
Meanwhile, one player unhappy with his current situation at Tynecastle is midfielder Julien Brellier.
The 24-year-old has been axed in recent weeks and is less than amused.
"Every week there seems to be controversy at Hearts," Brellier told the Sunday Mail
"I don't know why I'm not playing. I spoke with the boss and he says it is his choice.
"I respect that - if he believes another man can do my job in the team.
"I don't know what I will do next year. I have one year left and, earlier in the season, I thought I wanted to stay.
"But I'm not happy about the treatment of some players. I'm also angry about my treatment.
"However, it has nothing to do with me being left out of the side. It's all about the club being honest with us."
