Mahrez is a big fan of the prestigious cup competition - the oldest national football competition in the world.
He’s won it once under Pep Guardiola, in the 2018/19 season - and he is keen to win it again.
He said: “It is a very good trophy, a very good cup. It is a historic cup in this country.
“We won it once and it is something that we want to win more. We are going to go for it.
“I think it will be important to win. It is a challenge against a good team who are first in the league at the moment.

“They are the best team in the country at the moment. But they are coming to us on Friday, so let’s see what they can offer.”
Mahrez knows all about the challenge City face as they take on the Premier League summit team, Arsenal.
He’s looking forward to Friday – and, also, the battle ahead over the next months to be crowned Champions of England.
He continued: “I think they have been really good, but we are used it.
“Every year we have had a team [pushing us in the League]. It was Liverpool for four or five years and this year it is Arsenal.

“We are going to go for it. They are doing good, but we will see where it takes us both.
“At the moment, they are in front but there is still a long way to go.”
From a personal perspective, Mahrez is in a rich vein of form.
Across all competitions since the World Cup, he’s provided nine goals and assists across 650 minutes played – that’s 72 minutes per goal or assist.
He’s scored six goals, provided three assists and created 14 chances from open play, making him arguably City’s most important player of the moment.
Mahrez is happy to be firmly in form.
He added: “I had a few problems before and I wasn’t performing very good before.

“I came back really good, fresh and it is good at the moment.
“I am contributing and helping the team, so I have to keep going.”
