The main measures taken by health authorities following the classification of COVID-19 as a pandemic have changed the conditions for football players around the world. However, it is important to have training still, but in safe conditions.
It is important to continue training despite the current situation. Most physiological variables that are important to football performance are particularly sensitive to inertia. In a scientific study of Danish elite players, it has been shown that the level of physical performance decreased by 20-25% after two weeks of inactivity (Thomassen et al., 2010; Christensen et al., 2011). In addition, a decrease in several important physiological variables was observed. In contrast, a group that received significantly less training than usual during the season, but at a very high intensity, showed that they improved their physical performance as well as maintained or improved several key physiological variables (Rago et al., 2019).
Here is the research that may be useful for you at this time, the issue is how footballers can run high intensity programs without the guidance of fitness coaches.
