Some teams are going to face a huge number of matches once the 2019-20 campaigns are permitted to resume, and domestic cups and continental competitions such as the Champions League and Europa League are due to be completed.
FIFA spokesperson said, “When competitions resume, such competitions are likely to face a congested match calendar with a higher than normal frequency of matches played in consecutive weeks.”
He further explained, “Safety of the players is one of FIFA’s main priorities. One concern in this regard is that the frequency of matches may increase the risk of potential injuries due to a player overload.
“In light of this and the unique challenge faced globally in delivering competitions according to the originally foreseen calendar, FIFA proposes a larger number of substitutions be temporarily allowed at the discretion of the relevant competition organiser. In competitions where less than five substitutions are currently allowed, each team would now be given the possibility to use up to five substitutions, with the possibility of an additional substitution remaining during extra time where relevant,” he added.
The rule change would apply until December 31, 2021 after FIFA’s proposals. There would still only be three breaks in play per team permitted for substitutions in order to prevent matches from becoming fragmented.
Further, World Cup 2022 have also been affected due to the pandemic COVID 19
All over the world so many tournaments and sporting events and activities have been either cancelled or postponed due to the coronavirus outbreak. Tokyo Olympics and European championship have also been postponed.
