To match the Swiss Football League's license requirements introduced in the 2012/13 season, the stadium was modernized in three stages.

On Monday evening, 2 March 2015, for the championship match against FC Schaffhausen, the new eastern standing terraces ware officially inaugurated and taken into operation.

[2] The most important issue in the preparation of the new season was only achieved two weeks before the start of the championship, although the change in the position of the head-coach had been announced some time in advance.

Other important signings were João Paiva, who had been FC Wohlens' top scorer the previous season, center-back Dennis Iapichino, who had spent the previous two season in the Major League Soccer, by Montreal Impact and D.C. United and Marco Köfler from Kapfenberger SV.

[3] The three most prominent departures were that of 33-year-old Sawas Exouzidis, who could no longer find a place in the team that Jürgen Seeberger had massively rejuvenated, Kristian Kuzmanovic, who left the club to play for Vaduz after his father had been fired, and Marco Aratore who transferred to St. Gallen in the top level of Swiss football.

Although FCW was able to hold the fourth position in the table despite this victoryless phase, the gap to the leader increased from 11 to 33 points and they lost all contact to the extended top group.

In the end, Der Landbote reported a "decent season" for the FCW, but once again missed the "necessary winner mentality".

Servette did not obtain a license for the 2015-16 Challenge League season, due to the fact that they did not provide the necessary financial documents and guarantees.

[6] Winterthur entered into the 2014–15 Swiss Cup on 23 August 2014 in an away game in the first round against lower tier FC Eschenbach.

Mohamed Elneny brought his colors into the lead after half an hour with a remarkable drop kick from outside the penalty area.

The defense in front of Basel's goalkeeper Germano Vailati held things tight and so after the first half hour, there was no longer any doubt as to which of the two teams would reach the next round.
