Leverkusen On 17 December 2012, German Bundesliga side Bayer Leverkusen confirmed they had signed Milik on a contract until summer 2018, for a reported transfer fee of €2.6 million. Milik failed to impress at Leverkusen though, making only 6 appearances before being demoted to the Leverkusen reserve team. Loan to FC Augsburg On 30 August 2013, FC Augsburg signed Milik on a one-year loan deal. The loan fee was reported to be €150,000, and composed of a base amount that decreased the more games Milik played for Augsburg and increased if Augsburg maintained its Bundesliga status. During his spell in Augsburg, he was capped in 18 matches, but he only scored 2 goals. However, he scored an equalizer in the 88th minute in a 2–2 home draw against Borussia Mönchengladbach, helping Augsburg earn a vital point.
