VIEW FROM THE DRESSING ROOM
Lincoln City manager Gary Simpson told BBC Radio Lincolnshire:
"I thought we acquitted ourselves quite well. There's never a nice way of losing but we certainly didn't go down without a fight. I thought at times we played some decent stuff and created some opportunities and on another day we might have got one.
"We worked on a gameplan because we knew they were big and we might have to get down the side to cause them a problem and I think we did that.
"They were always dangerous, don't get me wrong, they're a good team and it's a case of now that we've been beaten, how we react to that, but we've shown today that there's no need to be afraid of teams like them."
