Convey was traded to Ryan Nelsen's Toronto FC this week.
"I know that Sporting KC wanted to get rid of me, so it was more of a difficult situation," he told reporters. "They just didn't take care of the issue at the beginning of the season, so I was just sitting there waiting. I'm very happy to be here. I was kind of just waiting to come here.
"For me, [the trade] is just going from somewhere I wasn't wanted and wasn't playing to somewhere I am wanted. You get instant confidence from that and from a coach who tells you that he wants you to come in and play tomorrow."
