Sánchez's first competitive appearance was against Manchester City in the Community Shield, on 10 August, playing in the first half and helping Arsenal to a 3–0 win. On 16 August, he made his Premier League debut against Crystal Palace, assisting Laurent Koscielny's equaliser in a 2–1 home win. He then scored his first goal for Arsenal on 27 August, slotting the ball past Beşiktaş goalkeeper Tolga Zengin in stoppage time of the first half to secure a 1–0 aggregate victory and a spot in the group stage of the 2014–15 Champions League. Following the game, Wenger was full of praise for Sánchez, with the Arsenal manager saying, "He had a good game, not only on the technical side but on the fighting side. He was mobile, dangerous and has shown as well he has great fighting spirit, qualities that will be very important in the Premier League." His first league goal came four days later, netting the opening goal in a 1–1 draw away to newly promoted Leicester City. He then scored his second league goal in as many games against previous season champions Manchester City, demonstrating perfect technique to sidefoot a volley high past goalkeeper Joe Hart in a 2–2 draw at the Emirates Stadium.
