Linnes arrived in Istanbul to sign his deal with Galatasaray.
However, the Norwegian right-back played a staring role in Molde's win over Fenerbahce this season in the Europa League and got himself on the scoresheet.
Galatasaray are expected to make major revisions to their squad following a disappointing start of the season. The Istanbul giants find themselves in third place with 30 points in 17 games.
The Lions are 11 points off Turkish Super Lig leaders Besiktas and ten points behind rivals Fenerbahce. Galatasaray take on Sivasspor in their next Turkish Super Lig fixture.
