The Hungarian midfielder played six games on loan for Greuther Furth last season in the Bavarian club's unsuccessful fight against relegation from German football's top flight.
The 25-year-old has returned to parent club Debrecen in his home country, who he claims will not stand in his way if he wants to play overseas again.
"I played the last half season in Germany and I would like to play abroad again," Varga told Debrecen's official website.
"Fortunately my present club are positive and supportive of me. I'm happy that there are approaches and interest from other clubs. I think my future may be decided within a week."
The challenge posed by a rigorous 46-game campaign in England's second tier appeals to the Hungary international.
He added: "The Championship is tough but it's also very popular and seen by many fans. There are a great number of teams so they play a lot of games.
"I think playing there would be a forward step in my career, I would consider this a great possibility."
