Joe Hart accepts Manchester City have "won nothing yet" after they beat Manchester United in their FA Cup semi-final at Wembley.
City conducted triumphant celebrations at Wembley after Yaya Toure's 52nd-minute goal sent Roberto Mancini's men into the final but there was a word of caution from Hart alongside the expected glee.
"It means the world, just look at us," said Hart after a match that also saw United veteran Paul Scholes sent off for an ugly challenge in the second half.
"The boys are over the moon, the fans are over the moon and the staff are over the moon but we've won nothing yet," Hart told ITV1.
"We've done nothing yet but we've got got ourselves in a good position in the league and in the final and I'm so happy for the people (fans) here."
Turning to Toure's goal, coming on the back of a Michael Carrick error, Hart said: "It was a fantastic goal, he was fired up at half-time. He's an emotional guy and he lets his emotion show on the pitch."
Manchester United goalkeeper Edwin van der Sar conceded the result was even harder to take than a normal semi-final defeat due to the identity of the opponents.
"It is never nice to lose the game but a semi-final against City is even worse of course," he told BBC Radio Five Live.
"We had our chances in the first half and the tempo of the game was too slow for us. We should have sped up more.
"They scored in the second half because of a couple of mistakes from us and then it was difficult 10 versus 11.
"You don't like to concede but if it's a 25-yard screamer you can sometimes live with it but it was a scrappy goal and we didn't really clear the ball out of defence."
Van der Sar also said the Red Devils were not mourning the end of their treble dream, suggesting it was primarily of interest to the media.
"You guys have been talking up the treble of course, making comparisons with 1999 but now we start again tomorrow. We go to Carrington, do a normal warm down, take a bath, then go to play Newcastle."
