The midfielder was sought after by several clubs in the summer, but he has not featured in the Premier League since early November, and has come out recently saying he is being misused at Anfield.
When Liverpool sealed the loan signing of Nuri Sahin in the summer it was rightly seen as quite a coup for the club. Plenty of other big teams in the Premiership had been interested in the player, and his reputation was high enough that he had been seen at one stage as the man to replace Luka Modric at Tottenham Hotspur.
Arsenal were also close to signing Sahin at one stage, but both North London clubs may now be happy they missed out on the Turkish midfielder as he has failed to have an impact at Liverpool, and has become increasingly unsettled at Anfield in recent weeks.
Sahin has publically spoken out about his belief that he is being played in the wrong position at Liverpool. At BoRussia Dortmund, and also in his limited appearances for Real Madrid, Sahin was used in a holding role in the midfield, but Brendan Rodgers has primarily played him in a more advanced position behind the lone striker Luis Suarez.
The midfielder has now complained that he is not comfortable in that position, and would prefer to move back to holding role he is accustomed too.
How this public complaint will affect his stint at Liverpool is yet to be seen, but Sahin hasn't featured at all in a Premier League match since going off in the 59th minute in the 1-1 draw with Chelsea at Stamford Bridge, and it's hard to see how speaking out against his manager will aid his cause.
Sahin is clearly behind both Lucas Leiva and Joe Allen in the pecking order for his favoured holding role, and with the likes of Shelvey, Suso and Sterling impressing in the more advanced roles in the midfield, it's difficult to see where he fits in.
Since leaving Dortmund as one of the most exciting prospects in Europe Sahin's career has hit the buffers due to a combination of poor luck with injuries and competition for places at the clubs he is at.
The move to Liverpool was seen as a good one for all involved parties in the summer, but so far it seems that neither Liverpool or Sahin are living up to each other's expectations.
How can Sahin and Liverpool move forward from here?
