Despite the 7-1 mauling, Guy managed to make a name for himself on a global stage.
With throw-ins usually one of the dullest parts of the game, when anybody tries something a little bit different you can be sure it will make its way on to YouTube pretty quickly.
American Ryan Guy made a name for himself on a more global stage than he is used to, during his appearance for the League of Ireland Airtricity XI against Manchester United this evening.
They may have been on the end of a 7-1 drubbing by the Red Devils but Guy took the opportunity to illustrate his personalized throw-in complete with forward somersault.
This is far from the first time that Ryan Guy has pulled out his acrobatic throw-in, it is a regular feature in his matches for St Patrick's and he is also known to somersault when he scores a goal.
The awesome footage of Ryan Guy's forward somersault throw-in, which apparently left even Manchester United boss Sir Alex Ferguson bemused, is on the video below.
