The 21-year-old moved from Köln's academy system to Bayern in the summer of 2013 on an €800,000 transfer. He only got about a year of first team experience, half of which came on loan at Kaiserslautern. He would now get the chance to play consistently in the Bundesliga with Hertha BSC, flanking former Dortmund striker Julian Schieber in the Olympiastadion.
Weiser has a goal and four assists in 17 appearances with Bayern, including the game-winning assist against Hertha BSC that won Bayern their 25th domestic league title. He started six matches in a row between Match Day 28 and Match Day 33 in the absence of Arjen Robben, and even got the nod in the DFB-Pokal semifinal against Borussia Dortmund.
Weiser is one of three players – Lukas Raeder and Sinan Kurt – Bayern poached from other academy teams in the last three seasons. He would join Raeder as players Bayern did not extend after their initial contracts should his move to Berlin be finalized.
