Amazon Prime introduced a brand new feature to their coverage of Tuesday night's Premier League coverage and it has certainly gone down well with fans.
For the first time ever, a substitute counter was added above the scores during the two matches.
The addition allows viewers to easily keep track of how many changes their side has remaining.
The tracker displays five small marks above the name of each team - with one disappearing each time a substitute is made.
This was demonstrated quickly as Burnley's Luca Koleosho was forced off after just 36 minutes.
