A FA Cup-Halve Final is further evidence that Nottingham Forest is back in the long time. These large occasions were commonplace in the heyday of the club, but this great club has not enjoyed such intoxicating days for more than 30 years.
It has been an incredible season for the side of Nuno Espirito Santo, who fights for a Champions League place, but also the chance to eliminate a trophy that even the big Brian Clough never succeeded in Forest.
This is not just a day to walk to Wembley and wave to the fans – this is a huge opportunity for Forest and a game that they can win.
They have to show their murderous instinct and the way they performed against Tottenham was the perfect rehearsal to compete against Manchester City.
That would have been a satisfactory moment for Nuno to get his former club better and he proves that he has developed a lot of tactically from his Wolves days, while creating an enormous spirit, desire and determination among his troops.
Against Spurs they showed again how they are willing to suffer without the ball and to get their sea from red bodies back to the edge of the area that is ready to strike when the moment occurs.
They are like a boxer on the ropes, but when they see that an opening ends up the knockout outlook.
Nuno made smart adjustments to get more midfield bodies to combat the entire back of Tottenham. He started to sit midfielders Danilo and Nicolas Dominguez, and by sacrificing wing player Callum Hudson-Odoi, Elliot Anderson and Morgan Gibbs-White.
When they attacked, Harry Toffolo gave them width from the left while Gibbs-White went into the front line and broke the forest at a breathtaking pace. The fast Anthony Elanga started at the top next to ruthless Finisher Chris Wood in a few split strikers.
Forest forced traces in wide areas, which resulted in a record of 51 crosses – most in a Premier League match this season – those meat and drinks were for Forest's central back.
Nuno can pack the midfield again if Pep Guardiola uses full backs Nico O'Reilly and Matheus Nunes as he did in the recent victory of City over Everton.
They patrolled the center of midfield on Goodison and had Ilkay Gundogan and Kevin De Bruyne operated in the front line, but still found the time and space for nunes to break through and cross for the winner of O'Reilly.
Guardiola adds more variation to how he uses his entire backs and against Villa they held on to the touchline and gave the city width.
Bernardo Silva, who had started on the right in the last game, was sitting next to Mateo Kovacic while Nunes scored a very important goal.
The manager said Nunes was not smart enough to play in midfield, but he has been crucial in helping and scoring the winner in the last two games of the city to keep them in the mix for a Champions League place. I expect that he will be full of confidence at Wembley.
There is still a vulnerability about the city that we have never seen before in the office of Guardiola. If his entire backs come too far on the field, that leaves room for forest to exploit when they rise forward, as they have done the entire season.
