Christophe Henrotay was quoted earlier this week about Batshuayi, revealing that a number of clubs were chasing his signature.
Arsenal and Borussia Dortmund have both been strongly linked with the 20-year-old Belgian - which prompted Henrotay's comments.
He told Sudpresse: "There are Premier League clubs that are following him closely, but that's all. The interest from other big leagues is more serious.
"I'm still surprised by the way Standard communicates about Michy. The situation is very simple: if a club triggers his release clause, he can start negotiating with a club. I've the mandate to negotiate a transfer.
"At this moment there are no clubs that offered the full amount to trigger the clause. My player is still happy at Standard. For sure. But there's a lot of interest in him. It's getting hot. When a club decides to trigger his clause, it's up to Michy to decide."
But Standard have reacted angrily at Henrotay's remarks and released the following statement: "Standard Liege wishes to challenge FIFA regarding practices of Mr. Christophe Henrotay, licensed FIFA agent.
"Mr Henrotay has, in recent months, made a number of representations to several clubs (in English Premier League for the most part) to offer them to acquire Michy Batshuayi.
"Mr Henrotay tries to convince him to break his contract with Standard Liege, while it has recently been reviewed and extended until 2017.
"The club regrets this approach, the more so when the player himself has repeatedly said and repeated his desire to finish the season with the goal of delivering a title to Standard and finish as top-scorer.
"Henrotay has no mandate from Standard for such negotiations.
"The ultimate goal of the agent in question seems to want to sell the player and then loan him to another club in the Belgian competition.
"Standard Liege therefore wishes to present this case to FIFA."
