An oppotunity to play soccer in england.?

hello everyone i am 19 years old i just graduated from high school and i got an email to go for a soccer trial in england for the manchester youth acadamey. i play soccer very well i am an attacking midfielder i prefer playing left or right wing. i can dribble,p,control,and shoot very well. i am 5''6 and i weight 145 pounds. yes i am short but i can go past deffenders who are a lot bigger than me i am skillful and i play with older or younger players than me. i am very concerned about this. i am surprised how i got the email with the persons information and phone number all listed in the email. i dont really know what to do now. should i go and give it a shot even though there is so much competetion out there and there are some great players but i feel that i have something to offer to this sport. i love playing soccer since i was 6 years old its in my blood. but having this email really make me wonder and think is it worth going and can i make it over there i am very concerned. it will be very helpful to get some opinions that can make me make up my minde. especially from someone with experience about this aspect. thank you all.....
