The Hammers go into the game having lost the first leg 6-0 at the Etihad Stadium two weeks ago and would have to pull off one of the greatest sporting come backs of all time to make Wembley in March.
But Allardyce believes he can use the game to field a number of players returning from injury, as well as give some game time to some first-team players who haven’t played regularly, as opposed to fielding a team of youngsters.
“We will not have anybody of inexperience out on the field, apart from probably Ravel Morrison, who’s still early in his career at this level of football,” he told West Ham’s official website.
“The rest of the team will be very, very experienced in terms of their games at this level.
“We haven’t got too many options to change the team, but what I have got the option for us fresher players that haven’t played on a consistent basis, with our problems recently.”
And Allardyce will also welcome back club captain Kevin Nolan and defender James Tomkins after their respective four and one-game suspensions.
“I have a couple of players back from suspension, which is important to me,” he added.
“They’ll have a top competitive game after being suspended, Kevin Nolan and James Tomkins, which eases the problems that we’ve had recently.
“Hopefully we can give Manchester City a really tough game Tuesday night and try to get something out of it.”
