Ertuğrul Sağlam (born 19 November 1969) is a UEFA Pro Licensed Turkish football manager[1] and former player who most recently coached Kocaelispor.

He spent nine years playing for Samsunspor during two spells, and helped the club to promotion to the Turkish top flight in 1991 and again in 1993 after relegation.

A few years later, the then Beşiktaş coach John Benjamin Toshack used Sağlam as a central defender.

After he was traded in exchange with defender Erman Güraçar from Samsunspor, he could not stop his tears at the airport.

In 2006, Sağlam was voted one of the top 20 most promising coaches by respected football magazine Champions.

On 16 May 2010, Bursaspor won the Super Lig after beating defending champions Beşiktaş 2–1 at home.

It was manager Sağlam's first full season in charge having taken over in January 2009, and it is the first time he, and Bursaspor, won the league.

In the 2005–06 season, Sağlam's first in charge and Kayseri's second in the Süper Lig, he guided them to 5th place in the table with 51 points.

Although domestically Beşiktaş had a good season, they became a part of football history when the team lost 8–0 away to Liverpool in the Champions League in November 2007.

They picked up 36 points; an average of 2 per game, while also recording a 2–1 victory over Fenerbahçe and a draw with Beşiktaş.

The end of the season saw Bursaspor finish in sixth position, missing out on a European place by just three points.

The first half of the season saw a 1–0 home victory against Istanbul giants Galatasaray, and also a 2–3 win away at Beşiktaş.

In late 2009, Sağlam was linked with the vacant Turkey managerial position after Terim's resignation, but he refused to comment on the speculation.

Going into the final game of the season, Bursaspor were just one point behind Fener, and needed to better their results against defending champions Beşiktaş.

Knowing that the match against Beşiktaş could prove decisive, Sağlam told FIFA.com: "I hope we can win the title before then and that it doesn't rest on those final 90 minutes.

"[6]With Fenerbahçe held to a 1–1 home draw against Trabzonspor, and Bursa beating Beşiktaş 2–1, the Green Crocs were crowned champions, by just a single point.

Their continued success has forced some of the Turkish Press to reconsider the team as a serious title contender and not just a one-hit wonder, and they spent the majority of the league in either the first or second position.

On March 29, 2011, Bursaspor and Saglam agreed to extend the contract with three years until the end of the 2014–15 season.

[13] On 12 May 2024, Sağlam was appointed as the head coach of Kocaelispor for the second time, signing a 1.5 + 1-year contract with the club.
