No agreement was reached before the deadline passed, but there is every chance that the Belgium international will be turning out in England in the near future.
Chadli is keen to test himself in the Premier League, rather than open the door to interested parties from Italy and Germany, and a deal could be put in place at the end of the season.
The 23-year-old's representative Daniel Evrard told calciomercato.it: "A lot of European teams are interested in him and I have had contact with German and English sides.
"The club that came close to signing him in the summer was Fulham, but in the end a deal didn't go through.
"Italian teams? I have not had any contact with Genoa but I know that AC Milan have sent scouts to watch him many times.
"His future? Nacer has a contract with Twente until June 2014, but at the end of this season he could go to a big team in a big league. His preference would be the Premier League.
"I don't think Twente will sell him in January because they are top of the Eredivisie and they want to play in the Champions League next season."
