Basaksehir are top of the Super Lig table despite scoring fewer goals than any other top-four side.
The Istanbul minnows owe a lot of their success to an impressive defensive record.
Goalkeeper Mert Gunok has conceded just 11 goals in 23 league games keeping 14 clean sheets in the process.
In total Gunok has conceded 12 goals and kept 15 clean sheets in 25 appearances across all competitions.
Taking the major European leagues – Ligue 1, Premier League, Serie A, Bundesliga, La Liga, Eredivisie, Super Lig and Primeira Liga – into account the Turkey international currently has the best record for least goals conceded per-game ahead of PSG keeper Buffon, Porto shot-stopper Ikea Casillas and Liverpool ace Alisson Becker.
In terms of clean sheets Alisson comes out on top having shutout the opposition 16 times in the league this term.
Buffon is second on the list in terms of his goals conceded to games ratio but he has played far fewer games to the other keepers on the list.
The Italian has made 12 appearances compared to Gunok, Casillas and Alisson.
Gunok has proved to be a bargain for Basaksehir who snapped him up on a free transfer from Bursaspor in the summer of 2017.

The 30-year-old spent much of his career in the shadow of Volkan Demirel during his time at Fenerbahce despite being highly rated.
The 1.96m tall keeper has six Turkey international caps under his belt but his last call-up was in 2015.
Gunok is expected to regain his place between the sticks for the national team for the next round of games.
