In professional sports, more and more data about the athletes and players is gathered every day. 
To increase that little bit of extra performance, to analyse the interactions with other players or to optimise diet and movement. 
More than other people, they are monitored during their competitions and trainings.
Wouldn't it be great if all that information would be brought together, on a person level and on a team level. 
If the player changes from club to club or gets another trainer or an additional coach, the data is shared in an easy way, and both the players as their coaches and teams can get that extra bit of feedback to increase the performance and results even more.
