2017 Liga 1 (Indonesia)
The 2017 Liga 1, also known as Go-Jek Traveloka Liga 1 for sponsorship reasons, was the inaugural season of Liga 1 under its current name and the 8th season of the top-flight Indonesian professional league for association football clubs since its establishment in 2008. It was the first official professional league season held post-FIFA sanction. The season started on 15 April 2017 and ended on 12 November 2017. Fixtures for the 2017 season were announced on 11 April 2017.
2014 Indonesia Super League winners Persib were the defending champions, as the 2015 Indonesia Super League was abandoned midway due to FIFA suspension while the 2016 Indonesia Soccer Championship A was not counted as an official league.
Bhayangkara won their first Liga 1 title with one match to spare.
The season was marred by the death of Persela's longtime goalkeeper, Choirul Huda.
Overview
Referees
In December 2016, PSSI and the league operator planned to use foreign referees for the 2017 competition. The use of foreign referee was intended to improve the quality of the competition. However, two weeks before the league starts, this plan was cancelled.After a wide criticism, protest and dissatisfaction towards the local referees during the first round of the season, PSSI revisited the idea. On 18 July 2017, PSSI and the league operator officially announced the use of foreign referees and assistant referees in select matches for the second round. There were two sets of officials, each coming from Australia, Kyrgyzstan, Iran, and Japan.
Player regulation
League operator also introduced several new regulations, such as requiring clubs to contract a minimum of five U-23 local players with three of them having to play as starting lineup minimum of 45 minutes in a match, restricting clubs to have more than two players older than 35 years old, and increasing the maximum number of substitutions to five for each team in a match.On 30 July 2017, in preparation for the 2017 Southeast Asian Games, all regulations concerning under-23 players were suspended. Later on 31 August 2017, PSSI decided to extend the suspension of all regulations concerning under-23 players until end of season.
Substitution rule
FIFA approved the five substitution rule on 12 April 2017. However, the two additional substitutions were only allowed for U-23 players.Teams
