Anderlecht captain Steven Defour could leave Belgium due to the abuse he has received from a minority of the club's fans, according to his agent.
Defour, 28, won two league titles with Anderlecht's major rivals, Standard Liege, before leaving for Porto in 2011.
The central midfielder joined Anderlecht in 2014 and on his first visit to Liege as an opposition player he was sent off after reacting to taunts from home supporters and a gruesome tifo that featured a caption reading "Red or Dead."
Last week, however, an anti-Defour banner was placed at the entrance to Anderlecht's ground, which made clear the displeasure of some of his own club's fans following his nomination as captain.
Defour also had cups of beer thrown at him by angry Anderlecht supporters during a defeat at Oostende last April and the player's agent, Paul Stefani, says his client is losing patience.
"Steven loves being captain at Anderlecht but some things happened with some supporters, like insults and drinks being thrown, that didn't please him," Stefani told la Derniere Heure. "He suffered greatly from that."
According to La Derniere Heure, Qatari club Al-Arabi are interested in signing the Belgian international, while Southampton are also said to be monitoring the situation.
Anderlecht want to retain the player but things could move swiftly should they lose their Champions League qualifier against Rostov on Wednesday.
"The question is to know whether he can still do good for these guys," Stefani said of the abuse Defour had endured. "He has the impression that nothing will be good enough.
"It was agreed with the management that we're going to put it to one side for a few days and we'll then see what happens.
"The directors see for themselves that he's unhappy. If there's a good offer for all the parties involved then we'll talk about it.
"Certain clubs have got in touch to know Steven's situation. If it's more probable to see him leave than to see him stay? In my opinion, the answer is yes."
