Both sides will head into this clash looking to maintain their unbeaten streaks - the hosts have not lost in their last three matches, while the visitors are unbeaten in the league this season.
Match preview
Kasimpasa finally recorded their first win of the new Super Lig season, thanks to Mortadha Ben Ouannes's sixth-minute goal that secured a 1-0 victory away at Caykur Rizespor last time out.
Prior to that, the Apaches lost 3-2 to Konyaspor at home in their opening match of the season, salvaged a 1-1 draw away at Hatayspor on matchday two, and settled for a 2-2 draw with Adana Demirspor on matchday three.
Recording this first league win helped Sami Ugurlu's side climb to eighth place with five points, but next in line is a baptism of fire against league leaders Fenerbahce.
Kasimpasa have barely had it good in this fixture, winning just eight of 84 meetings while losing 72 times, including in the last 10 encounters between both teams.
Making the task of ending this poor run appear even worse is the fact that the Apaches have failed to win any of their two home matches this season - first losing to Konyaspor before losing a two-goal lead to draw against Adana.
Jose Mourinho's Fenerbahce entered this season determined to dethrone city rivals, Galatasaray, who had won the last two Super Lig titles.
The Yellow Canaries have made a promising start, accumulating 10 points from four matches, placing them at the top of the table, one point ahead of second-placed Gala, who have played one fewer game.
Fenerbahce have impressed with their attacking prowess and defensive solidity, scoring eight goals in their last two league games without conceding - first thrashing Rizespor 5-0 before following it up with a 3-0 victory over Alanyaspor in their most recent league outing.
After four rounds of matches, Mourinho's men have the league's best goal difference, having scored 11 goals and conceded only two.
Mourinho, more than most, understands the importance of consistency and will push his team to maintain their unbeaten away record in the Super Lig, which stretches back to last year, when they take on Kasimpasa on Sunday.
