Fiorentina coach Vincenzo Montella won't take any risks against Europa League opponents Grasshoppers.
The Viola won the first leg 2-1 in Zurich.
"Will there be squad rotation? I need to take one game at a time. We cared about winning the Serie A opener, but the team for tomorrow will be set out like a Final. That's what we consider this game," said Montella.
"We will use the best players because we want to go through to the next round. The usual dangers await us and we cannot afford to lower our concentration levels, ever.
"Grasshoppers showed they play better away than at home. We've had two excellent results at the start of this season, though we are more practical and perhaps less spectacular than last year."
