Season Description The 2020–21 Eredivisie was the 65th season of the Eredivisie since its establishment in 1955. The season began on 12 September 2020 and concluded on 16 May 2021. On 2 February 2021, the KNVB announced that effective immediately clubs would be allowed to make an extra substitution for suspected concussions as part of an IFAB sanctioned trial. This trial will allow teams to make up to six substitutions across four breaks in the match instead of five substitutions across three breaks in the match. Ajax, having won the title in 2018–19, were the title holders, since the 2019–20 edition was cancelled due to the COVID-19 pandemic in the Netherlands after 25 matchdays and the title was not awarded.
