American football is aimed at increasing physical strength and a little less the technical and tactical part.
There are US champions who play in Europe such as Adams Tyler, a player of RB Leipzig who has grown tactically thanks to the German school and this means that the American national team is improving in all respects.
The player's agent Alessio Sundas has several contacts between American clubs, in particular he strongly believes in young talents from overseas and then promotes them in Europe.
At the same time, thanks to its network of collaborators, Sundas often starts negotiations to bring European top players to MLS such as Gonzalo Higuaín, Blaise Matuidi and many others.
