"Daley Sinkgraven is a very accomplished player technically. With his ability to read the game and quality, he'll fit in perfectly with our squad," said Bayer 04 sporting director Simon Rolfes in commenting on the transfer. "Beyond that, Daley already knows how our coach Peter Bosz likes to play and they both worked very well together in the time they were at Ajax," added Rolfes.
The former U21 international sees the move as "an exciting and motivational opportunity to be able to play for a top German club after my time at Ajax. Leverkusen have consistently been one of the best clubs in the Bundesliga for many years," said Sinkgraven. "I'm looking forward to playing in this league and, of course, to the challenges in the Champions League."
Bayer 04 have brought in a versatile left footer in Sinkgraven. "Daley was turned into a left-back in Amsterdam under Peter Bosz but he can also play in central midfield and wide on the flanks," declared Rudi Völler. "His versatility gives us further options. That is extremely important in terms of the opportunity to rotate with such a large number of games ahead of us," added the sporting managing director.

Bayer 04 were beaten 1-0 away at Union Berlin on Matchday 23 in the Bundesliga. Kasper Hjulmand’s side struggled to create clear chances, while the hosts struck the only goal of the game through Rani Khedira in the 28th minute.
