"It was a terrific start but the fact we've not played together before or worked together on the training pitch showed," Boothroyd said after the 2-1 defeat.
There's lots of positives. We played the best side in the division and we've ripped them apart in the first 20 minutes.
"We got lots of crosses in and we should have scored more goals but the positives are that from a defensive side we can do an awful lot better."
