Two second-half goals from John Stones and Feranndinho were enough for Manchester City to see off Man United 2-0 at home in the second Carabao Cup semi-final played on Wednesday night.
Both managers made two changes to the sides that featured in their last assignment, with City, who have been hit with positive Covid cases recalling Riyad Mahrez and Fernandinho in place of Bernado Silva and Rodrigo respectively.
United on the other hand had Dean Henderson in goal for David De Gea, with a fit-again Victor Lindelof partnering Harry Maguire in defense.
The match had a lively kick-off with both sides having goals ruled out for offside inside the opening five minutes.
United went first in the third minute as Martial slid the ball through for Rashford, whose shot was blocked by Steffen, but the ball rebounded back off Stones and went into the back of the net but the flag went up.
Two minutes later, Gundogan tapped in a Phil Foden's cross, but the flag correctly went up again.
United quickly attacked and almost got the breakthrough in the ninth minute, but Steffen pulled a world-class save to deny Bruno Fernandes from the edge of the box.
Man City then came closes to find the back of the net in the 13th minute, but Kevin De Bruyne's fierce shot from the edge of the box cannoned off the upright as the hosts survived.
City were once again denied by the offside flag in the 23rd minute as Fodden broke through to easily beat Henderson, but he was offside the goal did not stand.
The game's tempo dropped a little after the half-hour mark, but it was City who were in the ascendancy as the match approached the break.
City picked the second period from where they left off the first, and they were ahead within minutes of the restart.
Foden whipped in a dangerous ball into the penalty area and it went all the way through to Stones, who bundled the ball past Henderson from close range, and the goal was allowed to stand after a VAR check.
Guardiola's men grew stronger by the minute and had good chances to put the game to bed, with Henderson denying Mahrez and Gundogan in quick succession.
There were few clear cut chances in the remaining half as City chose to run rings around their opponents as they saw off the match.
They then doubled their lead with six minutes to go as De Bruyne's corner was headed clear by martial and then Wan-Bissaka, but the ball dropped invitingly to Fernandinho on the edge of the penalty area, who unleashed a first-time shot through the crowded penalty box and into the right corner.
City held on to pick a deserved win and make it to their fourth consecutive Carabao Cup final, where they will face Tottenham, who saw off Brentford in the first semi-final match on Tuesday night.
