Ospreys instead come to their third home game of the season with two defeats in front of their home crowd against Munster and Connacht.
In this first phase of Guinness PRO12, Alun-Wyn Jones and his team mates grabbed only one win; in Treviso in the fourth round.
Eleven internationals who took part in the Rugby World Cup could return available to coach Tandy for the challenge against Zebre.
It will be a special game for the Welsh scrum-half Brendon Leonard, former Zebre player who wore the white & black jersey in 47 official games during the past two seasons. The New Zealander was starter for the Italian side also in the only victory of the Parma based against the Ospreys at home in May 2014.
Respect to the match of last week Zebre will be without two injured players for the Swansea trip: back rower Cook and winger Berryman.
Zebre Rugby team manager Andrea De Rossi presents the pitfalls of the Swansea game: "Tomorrow we will find a special atmosphere: the Ospreys -strong team and a club with great tradition in this competition- arrive by 5 defeats in the first six races of the season and surely will deploy all national Welsh for this delicate challenge. Zebre are presented for the first time ahead in the table standings but the two last Parma wins just belong to the past: we must continue to be hungry for results, keep our feet on the ground with strong concentration, a key factor to achieve success in these high level challenges. It has been a good week of work; once again based on the study of the opponent and on our technical certainties".
