The Daily Star says Defour will wait to see if an offer from Tottenham materialises before deciding his future.
"Steven will tell his club he wants to leave because he wants to play in the World Cup," agent Paul Stefani said.
"Aston Villa? It can become real. There was interest from a few other clubs in England but to say that he may sign there tomorrow? No.
"Anderlecht has been the most concrete from the beginning. They always said they wanted to have Steven.
"Of course Anderlecht has a chance but Steven receives phone calls from other agents who promise him a transfer to Tottenham.
"It is normal that when you hear the name of Tottenham, we want to think."
