Alan Pardew: "I think it's difficult - obviously Arsenal have done it and Chelsea have come pretty close before.
"But not in all competitions - that is impossible and I think Jose has admitted that. But they're making a very good job of it at the moment.
"It's the best Chelsea team that I've ever seen and I've watched them since I was about 12 so I know them pretty well. I think Jose is pretty pleased with what he's got."
