After a few seasons during which they reached a certain level of stability, Sion have returned to being their turbulent normal selves, as they had three different managers this season, with the general consensus being that they did not do as well as they could have.
Didier Tholot, who was in charge for more than two years, was fired early in the season due to a poor start, but the appointment of Peter Zeidler changed everything, with the Sitteners going on to have a brilliant remainder of the first half of the campaign and finish the autumn season as third, with a second-placed finish ahead of Young Boys Bern definitely looking like a realistic possibility.
However, things fell apart for them in the second half of the season. The Sitteners struggled throughout spring, with only the equally poor form of Luzern keeping them ahead in the race for third so far. Sion managed to finish above the Blues, but could not fend off Lugano's surprise challenge and finished two points below the Ticiners, blowing a big opportunity to leapfrog them in the final round, when they drew against a Grasshopper side that had nothing to play for, when a win would have seen them finish third.
Zeidler was put on gardening leave with just over a month to go, but his replacement Seba Fournier did not really change Sion's fortunes, as he managed to win only one of his six games in charge and also oversaw Sion losing their perfect record in the Swiss Cup finals, as they were beaten by Basel with a 3:0 scoreline. The end to their campaign was particularly disappointing, as they lost at home to Luzern, drew at St.Gallen and also drew against Grasshopper, when winning only one of those games would have resulted in Europa League qualification.
All things considered, Sion's season was not disastrous by any means but their fans will be very frustrated at the amount of opportunities that their side had, and failed to take, to qualify for the group stage of the Europa League.
