The Ivory Coast international has found first-team opportunities hard to come by at Benfica this season and has made no secret of his desire to move elsewhere.
He was strongly linked with a January switch to Blackburn, but saw that deal fail to materialise.
Reports suggest Wigan boss Steve Bruce was also close to securing the services of the defender before the winter window slammed shut, with the Latics believed to be keen to resurrect their interest at the end of the season.
Zoro would be open to a move to the JJB Stadium, admitting that he is desperate to be playing regularly in order to give him the best possible opportunity to be involved with his country.
"I am very interested in playing in the Premier League," he told skysports.com.
"I am not playing much at Benfica, but I will fight to earn my place back and then see what happens in the summer.
"The next year is very important. I need to get in the national squad for the 2010 World Cup, as that tournament will be very important to my career.
"If I don't play the national manager will not call me, so I have to play."
