Manchester City boss Pep Guardiola says there'll be no underestimating West Ham.

The Hammers came back from 3-0 down against Tottenham last Sunday, but the former Barcelona boss from impressed with their whole performance, despite them conceding three goals in the opening 15 minutes.

"West Ham has incredible quality players up front," he said.

"They played really well against Tottenham - not just in the last minutes.

"At 3-0 down, they showed a lot of personality. They are in good form - a good moment for them."
