FCM won the first-leg of their round of 16 tie 1-0 thanks to an 80th minute Cho Gue-sung header.
Hutchinson said afterwards: "It's very frustrating. We had a lot of chances but didn't put them away, and we got punished for it.
"It was tough, but that’s no excuse. We had many chances in the first half and even in the second. We knew if we didn’t punish them, they could punish us with just one chance, and that’s how it goes.
"In training, we've been working on finishing, but today just wasn’t our day. They defended well and had a few blocks on the line, so credit to them. Hopefully, we can put it right next week.
"We have a lot of confidence and belief that we can turn it around."
