"I think what we've seen here is us getting beaten by a side that has been two or three years in the making," Coleman said to the club website.
"We had a couple of good early chances and their 'keeper has had to make a good save and we've had another one cleared off the line.
"But when they went ahead in the first half they bossed it really right up until half-time and I think they showed their class.
"That is the standard where we need to be and obviously we're not there yet but I think the scoreline was a fair reflection of the game."
