Initially playing as an attacking midfielder, his position was made more defensive in the 2017–18 season, but a dispute with the Schalke hierarchy the following April saw him fall out of favour and subsequently run down his contract, becoming a free agent that summer.

[4][5] Meyer's form at u-19 level, which saw him score 11 goals and create 11 assists in 15 appearances for the season, earned the attention of general manager Horst Heldt who signed him to his first professional contract.

[6] Following the departure of fellow midfielder Lewis Holtby to Tottenham Hotspur and the injuries of several other players, Meyer was included in Schalke's Bundesliga and UEFA Champions League squads for the 2012–13 season.

He made his debut for the club on 16 February 2013, coming on as a substitute for Raffael and assisting Michel Bastos for a late goal in a 2–2 draw with Mainz 05.

[4] Still aged 17, Meyer left school, the Gesamtschule Berger Feld, later that year before finishing his school-leaving examinations in order to focus on his football.

He was then substituted off after just eight minutes as the club looked to hold on to the win, with German media later labelling his assist as a "€20m pass" as it helped Schalke qualify for the Champions League proper.

[12][13][14] Following his impressive performance against Chelsea in the Champions League, he became a transfer target for the West London club, who were willing to pay Schalke €15 million.

[21] His most significant contribution was in a Champions League group stage match against Maribor, where he scored the only goal to take Schalke through to the round of 16,[22] but they ultimately came up short against Real Madrid, losing 5–4 over two legs.

In the 2015–16 season, Meyer scored goals against Hertha Berlin,[23] Bayern Munich,[24] Darmstadt 98,[25] Hamburger SV[26] and Köln.

According to Sky Germany reporter Dirk Grosse Schlarmann, the positional change better suited his qualities with an improvement in form, and because the crowd did not expect to him to win the match, he had more time to look and think about the opening pass when Schalke went on the attack.

However, in April, Meyer publicly criticised sporting director Christian Heidel and was left out of training for the rest of the season, which allowed him to run down the remainder of his contract until its expiration in June.

[47] In the gold medal final, played on 21 August, Meyer scored the equaliser that extended the decision to penalty shootout, which Germany lost to Brazil U23, 5–4.

[49] When asked about his good technique, Meyer replied, "At the age of 10 I dabbled in futsal for four years besides the football club.
