Raheem Sterling could be among stars needing in-season break

Some players may have less than two weeks off between seasons

Premier League clubs may have to arrange in-season breaks for their international stars to avoid burnout next season, the general secretary of the world players’ union has warned.

Players such as Raheem Sterling could face a situation where the 2019-20 season ends on August 23 with the Champions League final and the 2020-21 campaign begins with a Nations League match for England against Iceland on September 5.
