Pep Guardiola's side reached a second Champions League final in three years after demolishing Real and putting to bed questions from last years semi-final defeat to the Spanish giants.

Speaking on BBC Radio 5 Live's Football Daily podcast, Balague said: "I'm glad that the second half confirmed [this is the greatest Guardiola side] in a way. I think with the display we have seen it would have been a shame if the score didn't reflect it.

"4-0 tells you what happened and it could have been even worse than that. I would go as far as to say this is one of the best team performances I have ever seen. One of the top 10 performances ever."

Despite all the domestic success since Guardiola's arrival, there have remained question's around Manchester City in Europe's top competition, but Balague feels that has changed now.

"It is so difficult to have 11 players that think exactly the same way. Following an idea, a leader, that themselves will just add their personality because this team not only has a way of playing now, they also have a huge personality," he said.

"It was anger from Manchester City in the first half especially, saying 'we'll show you, we'll beat you', then after 2-0 it was not only 'we'll beat you' it was 'we'll kill you', then after three it was 'we haven't finished with you' and this was what we saw.

"[It was] historic on so many levels."
