Pep Guardiola’s City face Ole Gunnar Solskjaer’s United at Old Trafford on Wednesday night, with a place in the Carabao Cup final against Tottenham Hotspur on the line.
Spurs booked their spot in the final on Tuesday evening with a 2-0 win over Championship outfit Brentford and they will learn their opponents later on Wednesday.
City and United shared a point apiece in this same fixture in the Premier League earlier this season after a drab 0-0 draw.
Both are flying high in the table, with United level on points with Liverpool at the top of the league – with a game in hand on Jurgen Klopp’s side – and City four points further behind in fifth but with a game in hand on United.
The two sides head into this game off the back of wins. United beat Aston Villa 2-1 on Friday night before City humbled Chelsea 3-1.
And Leboeuf expect City – who he views as the superior team – to enjoy a similar win over United to book a final against Spurs.
‘I think that City is above both teams so I want City to show to the world that they’re back to – even though it’s not the Premier League they’ll be playing in – being contenders.
‘Therefore, the same team, the first XI. They don’t have much choice, they’re on a good road right now and they have to keep on going if they want to go through and maybe play a final but also reassure everyone about their future.’
