During the summer transfer window, the Super Eagles striker was linked with a move to several Turkish clubs, including Besiktas.

However, he moved on loan to rivals Trabzonspor and has been a revelation since becoming a key player in the team.  

The towering forward has already netted seven goals in just nine appearances for the Black Sea Storm this season.

Speaking on the matter, former Turkish midfielder Sinan Engin voiced his disappointment with Abraham's impact and contrasted it with Onuachu's success.

"Besiktas was a better team last season. So why did they spend money on transfers?" Engin remarked, as reported by Beyaz Futbol. 

"If they had continued with the same team and just signed one striker, but not Abraham. They should have signed a striker like Onuachu."

Istanbul giants Besiktas have struggled to meet expectations despite a summer spending spree exceeding €30 million. 

The club sits in sixth place with 13 points from eight matches, highlighted by a disappointing 2-1 defeat to newly promoted Genclerbirligi on Saturday.

One of their major summer acquisitions, English striker Tammy Abraham, has yet to find his rhythm. 

The former Chelsea forward has scored only three goals in eight games, a return that has drawn criticism.

While Onuachu's contributions have helped Trabzonspor occupy second place in the Super Lig standings, positioning themselves as serious title contenders.
