Pre-season and friendlies
On 26 June, Legia left for a 10-day training camp in Kranzach in the municipality of Kössen, Austria. The footballers stayed at the Hotel Seehof. Missing from the first-team players was Igor Strzałek, who was included in the Under-19 national team playing in the European Championships at the time. Before the trip, the players won a friendly against Lechia Gdańsk at the Legia Training Center. In Austria, Legia played three friendly matches. The first against FC Botoșani was won confidently 5–0, with a hattrick scored by Blaž Kramer. In the next match against Qarabağ FK, Legia were led by assistant coach Przemysław Małecki as Kosta Runjaić left the training camp for private reasons. Legia won 2–0, with newly acquired Juergen Elitim scoring his first goal for the team. The last and most difficult opponent during the training camp was the Austrian champion FC Red Bull Salzburg, against whom Legia, however, won 2:0 after a good game.

During the training camp in Austria, Israeli Ilay Elmkies was tested and played in a game against FC Botoșani, but the club decided not to sign him and the player left the training camp on 1 July.
