Kevin-Prince Boateng has remained positive in the wake of Besiktas' 1-0 Turkish Super Lig defeat at Istanbul Basaksehir, calling on them to "bounce back".
The 32-year-old was making his first start for the Black Eagles since joining on loan from Fiorentina.
Senegal forward Demba Ba was the man to score the game's only goal, with the result failing to move Besiktas off seventh spot on the log.
"Disappointing result, we will bounce back eagles!! It’s not over till it’s over," Boateng posted on Twitter after the match.
Boateng made his first appearance for Besiktas off the bench against Gaziantep last weekend, netting the second goal in the 3-0 victory.
He will hope to put in such a performance again when Sergen Yalcin's men host Trabzonspor at Vodafone Park on February 22.
