PREVIEW: Basel (SUI) v Fiorentina (ITA)

Meanwhile La Viola can do likewise with a win combined with a draw between Belenenses and Lech Poznan.

The Italians relinquished top spot in Serie A over the weekend after a 2-2 draw at home to Empoli, having trailed 2-0 at half-time in Florence.

Sousa admitted selection errors after leaving out Nikola Kalinic and Josip Ilicic, with the former coming off the bench for the second half and scoring twice to salvage a point.
