Khairul Amri

Tampines Rovers In the mid-season transfer window of the 2008 S.League season, Khairul Amri moved to Tampines Rovers and capped off the season by winning the S-League's Young Player of The Year. However, he sustained a metatarsal injury in the 88th minute of the third-place play-offs of the 2008 Singapore Cup against his former club, the Young Lions, which ultimately ruled him out of action for two months.

Persiba Balikpapan In 2010, Khairul Amri moved overseas for the first time to join Indonesian football club Persiba Balikpapan. Khairul Amri substantiated his decision to join the Indonesian side on the fact that it was a rare opportunity, not just for him to prove himself overseas as a footballer, but also to expand the profile of Singaporean football. The move would also allow Khairul Amri to be exposed to a different type of challenge as he had already been playing in the S.League for 5 years.

Khairul Amri had originally been slated to stay for a longer period with Persiba Balikpapan. Prior to the match that caused his knee injury, the management team had proposed a contract extension to him. However, he had told the staff to wait until the end of the game.

LionsXII Khairul Amri returned to the LionsXII setup once again for the 2014 Malaysia Super League season. He scored seven goals in 24 appearances for his team.

He started the 2015 Malaysia Super League strongly, scoring 10 goals in 25 appearances for his team, including a hat-trick in a 4–1 win against Sime Darby. His fine form was rewarded as he won the May Player of the month award. However, in October 2015, his knee injury struck again, forcing him to miss the rest of the season.

Young Lions After the LionsXII was disbanded following the conclusion of the 2015 Malaysia Super League season, Amri signed on a two-year contract with the Young Lions for the 2016 S.League season as one of three overage players, together with Firdaus Kasman and Christopher van Huizen. He was also named as the captain of the team. However, he was forced to miss out the opening weeks of the season due to an injury. Khairul only eventually made his first appearance in April, 5 months after his last competitive match. Khairul's injury ravage season saw him score only 5 goals all season.

He made his re-debut for the Stags in a 2017 AFC Champions League qualifying play-off against Filippino side Global FC and had a chance to net on his debut but his penalty was pushed away by the goalkeeper as the Stags crash out following a 2–0 defeat. His first appearance in the league, which was also a Singapore Community Shield match, ended in a similarly disappointing fashion as he came off the bench in a 2–1 defeat by Albirex Niigata Singapore FC. Khairul came off the bench and scored the winner and his first goal of the season during the Stags' first game of the 2017 AFC Cup campaign. He scored his first goal in the league in a 2–1 win over Hougang United FC.

His next goals came in a 1–3 win over Felda United, where he scored a brace in 4 minutes, which kept Tampines in the hunt for a spot in the next round. His exploits against Felda in a 24 minutes cameo earned him recognition as he was named the Fans' Asian Player of the week. He continued to prove himself as the team's talisman as he scored the only goal in the next game, a 1–0 win over his former club, Young Lions, to push his team to 3rd place in the league.

He has committed his future to the club by signing a three-year extension, starting from the 2018 season. However, Amri decided to leave the Stags for Malaysia, after catching the eye of Pahang-based club, Felda United who were impressed by the veteran who had scored 8 goals in the opening months of the Stags' 2019 campaign.

Felda United Amri left Tampines Rovers midway through the 2019 Singapore Premier League season to join Malaysia Super League side Felda United, signing a -year deal for the club rooted at the bottom of the table.

Tanjong Pagar United In 2021, Amri joined Tanjong Pagar United. He ended his 2022 campaign with 6 goals and 3 assists in 24 appearance for the club.

On 6 April 2023, Amri, the oldest outfield player in the 2023 Singapore Premier League at age 38, eluded the Hougang defence just enough to launch a spectacular scissors-kick volley to sweep the ball home.
