Oğuz Han Aynaoğlu

Nordsjælland

Following this debut, Aynaoğlu made two additional appearances in the spring of 2011. His strong performances earned him a place in the first-team squad for the 2011–12 season. However, during his time at Nordsjælland, he struggled to secure a regular spot in the starting lineup. In the 2011–12 season, he featured in just one league match, and the following season (2012–13) saw him make seven appearances. In January 2014, after limited playing time and a series of injuries, Aynaoğlu left the club. Although he faced challenges in his final season, particularly with injuries, he did manage to play more frequently in the autumn months.

Bursaspor

On 5 January 2014 it was confirmed, that Aynaoğlu was sold to Turkish club Bursaspor. He played nine games on loan for Adanaspor in the first half season.

Loan to Adana Demirspor

After Aynaoğlu's first season at Bursaspor, the club underwent changes in management, including a new board and manager. Following this shift, Aynaoğlu was loaned out to Adana Demirspor after just half a season at Bursaspor. He later revealed that the new management had neither seen him play nor train, but decided to loan him out without consulting him. At Adana Demirspor, Aynaoğlu quickly became a regular starter and enjoyed a successful stint, which he later described as a breakthrough in Turkish football. Over the course of his loan, he made 40 appearances and scored six goals before returning to Bursaspor.
