Manchester City boss Roberto Mancini is wary of today's opponents West Ham United.

After watching the Hammers' 2-2 draw against Manchester United recently - a match the Londoners could have won - Mancini knows they will be in for a tough afternoon.

He said: "I think West Ham have had a good season.

"They showed this against United two weeks ago.

"It'll be difficult. They are a physical team and Andy Carroll is a strong striker."
