I am 17. I used to play baseball in my school club but now I wanna change my sport and join a football club to become a goalkeeper.
Anyone can become a goalkeeper, but if you are talking about going on to play professionally then just take a look at some stats.
Brian Holt is currently the shortest goalkeeper in the MLS, at a height of 5’8″ (172cm)
The shortest goalkeepers in the English Premier League (Michael Vorn/Mike Bunn) are 6’0″ (183cm)
The shortest goalkeeper in the 2014 World Cup was Ivory Coast’s Boubacar Barry at 5’11 (180cm)
So you can see that the top leagues/competitions are dominated by taller goalkeepers, and this is simply because the taller they are, the longer reach they have and the better chance they have of keeping shots out. This also commonly applies to central defenders since they have a greater chance of winning headers.
A shorter player would be best suited in a winger role, like Emanuele Giaccherini (5’6″, 167cm) or Aaron Lennon (5’5″, 165cm).
Lionel Messi and Sebastian Giovinco play as forwards and are 5’7″ (170cm)
