City blew a 1-0 lead at Falmer stadium to lose 2-1 on Sunday.
Rodri said later: “It’s disappointing because we’re Man City and we come here to win. But this is the reality, we are not at the level for a long, long time.
“The only way to come back is to look at ourselves. That’s the reality.
“I think we started well but in the second half we dropped a little bit, and here at their home with the pressure and two big mistakes from us and then 2-1.
“We’re missing the level, I don’t know, call it what you want. It’s a matter of the team, changes, new players have to adapt and when you change the team that much it is difficult. This is our reality, it’s not excuses.
“I don’t think we had control of the game. I don’t think we were at our best, we didn’t create much. It’s many aspects. Today we should win because the two goals we conceded are two mistakes. Some of the mistakes are like kids mistakes. This is football. When we lose it is easy to point at everyone. The reality is we have to raise the level if we want to compete for the Premier League.
“We have to look to ourselves and see that this is not the way to achieve things. Let’s go to the international break, clean our minds and come back stronger.”
