“I’m disappointed we haven’t scored,” Sam told the official site. “Chelsea is a very difficult place to come to and you have to maximise the opportunities you get.
“Matt Jarvis’ service into the box today was really, really good and unfortunately we didn’t have any goals on the end of that.
“We had one struck off, which I thought was a really soft foul. I’m not so sure that if it had been outside the box he’d have given it. Then Andy’s had a header a couple of minutes later that went wide. There were two more in the second half, all from Matt Jarvis.
“He was our biggest threat today, every time we got him the ball today he skinned the full back. He put the ball where he should do, in the right areas with the right quality, but again the old Achilles heel for us of not scoring away from home has risen again.
“These kind of chances at Chelsea are difficult to come by, so when you do get them you have to punish the opposition and score them. At the moment we’re not doing that.”
