Sergio Aguero admits Manchester City's situation looks "grim".

City were stunned at Southampton on Saturday.

"Some days, nothing works the way it should," Argentina international Sergio Aguero said via his account, @aguerosergiokun.

"This was one of those days. There's no excuse - we need to work hard to forge ahead.

"It all looks a bit grim right now, but I won't believe giving up is an option."
