City were on top for much of the game, but were forced to work hard against the in form Hammers and Rodrigo was pleased with the character shown by the hosts.

“This is all about the team, all 24 players we have in the squad,” he added.
“We all need to be involved. Everyone is going to be important.
“People who maybe weren’t involved as much early in the season are now taking the responsibility.
“We have key players out, but we’re still winning and playing well - that’s the key to success at the end of the season.“
