New rules and new technology were supposed to reduce the number of controversial incidents in the Premier League, but players and managers appeared to be just as frustrated with refereeing decisions after a number of incidents on Saturday.
Manchester City had a goal ruled out for handball in their defeat at Tottenham, Aston Villa saw a late penalty decision overturned via VAR in their loss to Brighton, while similar incidents cost West Brom at both ends of the pitch as they were beaten 1-0 at Manchester United.
It led to an exasperated Manchester City midfielder Kevin de Bruyne questioning whether there have been too many law changes in football in recent years, leaving everyone to be unsure of where they stand.
