In order to rebuild the squad after a disappointing league campaign, and to prepare for the club's first in the UEFA Europa League, Arsenal used the following off-season to sign strongman left-back Sead Kolašinac from Schalke 04, while also purchasing striker Alexandre Lacazette for a club-record £46.5 million. The two players made their debuts in the 2017 FA Community Shield against league champions Chelsea, where Kolašinac scored to send the game to a penalty shootout. Arsenal scored all four of their penalties to claim their 15th Shield and their sixth trophy in five seasons. The club parted ways with seventeen players, including first-team stalwart Alex Oxlade-Chamberlain to Liverpool for a record sale fee of £40 million. The club, however, began the 2017-18 campaign poorly, failing to register an away win until December. After outcry from fans about the club's inabilities on the pitch, Arsenal went and appointed backroom trio Sven Mislintat, Raúl Sanllehi, and Huss Farhmy, to act as head scout, head of footballing relations, and contract negotiator respectively, in order to address the club's shortcomings.
