Ridhuan has thus far played five times for the club this season, twice as a starter, but has failed to impress coach Rahmad Darmawan in those matches.
"Ridhuan has been given the opportunity to play as a starter and also coming in as a substitute, but we decided to terminate his contract as he has failed to show maximal potential and is always injured," Arema’s media officer Sudarmaji explained.
But despite the official announcement by the club on May 8, Ridhuan was still seen training with the club the day after and was surprised with the news.
"The management has not contacted me," he told Ongsinade News.
"It is better if the information comes from them. If it’s from others, it is not certain whether it is true or false; let them [the management] contact me on this.
"Personally, I won't be going back to Singapore as I still prefer to stay here [in Indonesia]."
Ridhuan last played in the S.League with Tampines Rovers in 2009 before making the switch to Indonesia with his current club.
When the club encountered a split in management and dualism in the local league, Ridhuan turned out for the Arema team that played in the Indonesia Premier League before signing for the ISL outfit at the start of the 2012-2013 season.
