Arsenal boss Arsene Wenger believes Manchester City are lucky to be top of the table.
City's stunning form has seen them open up an 11-point lead at the top of the table drawing inevitable comparisons with Arsenal's 'Invincibles' team of 2003-04.
"Look, we had no petrol but ideas, they have petrol and ideas, so that makes it more efficient," he said.
"So, everybody expects and projects that they will last. Why not? It can happen, but there is still a long way to go.
"At the moment I think everything goes for them inside the games, but maybe as well they have the quality to turn it in their favour."
