The 19 year old told BBC Wiltshire: "I've just got to come here and work hard."
Belford continued: "I've played a few games at Under 21 level and I've been away with the Liverpool first team so it's been brilliant for me.
"I've heard a lot of good things about Swindon and it's on the way up. I've seen the manager has got belief in the young players, so it's great for me."
"I'm not going to put any pressure on myself to do anything," he added.
"But if I can get some first-team experience that would be brilliant."
