Samatta joined Fenerbahce on loan from Aston Villa in September last year, with the move set to be made permanent at the end of the season.
The attacker, an £ 8.5 million arrival at Villa Park from Belgian club Genk in January 2020, joined the Turkish side on an initial season-long loan in September.
He hit the ground running, netting twice on his debut in the 2-1 Super Lig win over Fatih Karagümrük in early October.
But the Tanzania forward has added only two more goals in 16 league appearances since then in the victories against Ankaragücü and Kayserispor in January.
Samatta’s stay at Fenerbahce is due to be made permanent at the end of the season for around £ 6m with the 28-year-old having agreed a four-year contract.
According to Turkish news outlet, Aspor, Fenerbahce are now making contingency plans unless Samatta's fortunes in front of goal improve.
They report he has performed ‘far below expectations’ for coach Erol Bulut’s side.
The outfit is already considering moving him on in the summer window to be ‘replaced by a better striker’.
Samatta began his career as a youth player for Tanzanian club African Lyon in 2008. He turned professional in 2010 with Simba Sports Club, where he played for only half of the season before moving to DR Congo's TP Mazembe.
The attacker had spent a total of five years with TP Mazembe, initially becoming a first-team regular.
He was named the 2015 African based Player of the Year and finished the season as the top goalscorer of the CAF Champions League, as he helped TP Mazembe to win the title.
In January 2016, Samatta signed for Belgian side K.R.C. Genk, helping them qualify for the UEFA Europa League and win the Belgian Jupiler League in 2019.
Having finished the season as the top goalscorer of the Jupiler League, he also won the Ebony Shoe award in Belgium for his outstanding season with Genk.
In January 2020, he moved to Aston Villa, becoming the first Tanzania-born player to play and score in the English Premier League.
