"Their pace down the flanks was probably the difference between the two sides," said Pardew.
"The pace they have can undo you and your discipline as a back four and you want that in your team, you want that directness."

"I have spoken to Mike (Ashley) and made it very clear to him that Carroll has to stay and he has said that he is not for sale,” he added.
