"It was tough, very tough to play in heat like that, I struggled to breathe at times," Jones told MUTV.
"It was tough, very tough, but I still enjoyed it, being out there with the lads. It was nice to put the shirt on for the first time and as I've said previously, I feel at home now.
"I'm pleased we won. It just shows what the lads are about and what they're capable of to come back [from 0-1 down] in such a tough game. They [Chicago Fire] were a good team, they popped it around well. So credit to our lads, including all those who came on."
