"It would have been great to have gone in at half-time with the lead, but it wasn't to be," Coleman told evertontv.
"We had to go back out in the second half and fight and I thought we did well in terms of battling hard, but we didn't produce enough in the final third.
"I thought we did enough to keep them out, but, unfortunately, it wasn't to be our night."
"We've got a busy Christmas period coming up and the Premier League waits for nobody," Coleman added.
"We've got to dust ourselves down and go again."
