Hotshot Ousman Jallow has a goal more to topple leading goalscorer to the goal summit as the forward nab in his 14th of the season.

The ex- Wallidan ace's club led by an Ozmen opener in the 52th minute before Yalciner drew level for 12th positioned Karsiyaka in the 75th. Jallow and Cameroon's Bikoko partnership has proven a success although Bikkoko has begin to be reduced to a second-half player.
Jallow has nabbed 14 goals in his first season with Caykur in 29 league matches trailing his attacking partner by a margin of one with Bikoko on a tally of 15. The former Brondby ace has establish himself a spot in the team and will likely be a transfer target of courting clubs giving his impressive recording on goals.
