A time-varying covariate has also been constructed in the form of the age variable. Players at or over the age of 33 at the beginning of the respective season have been defined as ‘veterans’ as seen in Table 1. This variable gives us an idea of how age affects your overall play when it comes to receiving sanctions. At their ages, their footballing experience gained could give them the edge when it comes to avoiding a sanction as they know how the referee tends to act during particular situations. However, these ‘veterans’ could also see their performances declining, resulting in steps missed and late tackles, often resulting in an influx of yellow cards.
