ENPPI are reluctant to extend coach Stojko Mladenov's stay after the petroleum side suffered a string of poor results. The Bulgarian manager, whose current contract runs out by the end of the season, was given a vote of confidence last week. But ENPPI, on second thoughts, opted not to table a new offer for Mladenov right away. "We won't renew Mladenov's contract now," ENPPI's football director Alaa Sadek told FilGoal.com. "We are confident that he can guide the team till the end of the term, but we are yet to decide on his future." ENPPI, who lie ninth in the Egyptian Premier League table, lost their last couple of matches to minnows Ghazl Mahalla and Military Production.
