Phil Foden made his 300th appearance in all competitions for Manchester City. He's the sixth player to play 300 times under Pep Guardiola, and the first player under-25 to reach the milestone.
Pep Guardiola spoke to BBC Sport after Manchester City's victory against Leyton Orient: "We played a really good game, it was a typical FA Cup game - that's why this competition is unbelievable. We knew that they were strong and they'd run in the channels. They are a really good team and incredibly well managed but we created a lot of chances. I'm happy to go through."
On whether he felt his side struggled in the first-half: "I don't think so. The first 10/15 minutes maybe but after the fantastic goal that they had - we took the game and created a lot of chances."
On whether he was frustrated that he had to bring on Phil Foden and Kevin De Bruyne: "Absolutely not, that is why they are here. We talk this competition incredibly seriously and we thought it was the best decision to make. I am happy for Kevin's goal, his movement was really good.
On Nico Gonzalez's injury: "Welcome to the Premier League and the referees. Maybe he knew about the referees because I understand it's not easy. It's not easy to do something when you play against teams like in League One."
Man Utd come from behind to win after stoppage-time Maguire header
We asked for your views on Manchester United's match against Leicester in the FA Cup.
Here are some of your comments:
Man Utd fans
John: Dreadful in first half with some improvement in the second. Overall a very poor display; poor passing, little skill and lacking enthusiasm.
Mac: Never seen so many passes given away, territory squandered and such an obvious lack of strategy. Second half and Garnacho were totally different but still had to wait for a goal to ignite the team. Very lucky to get the winner - offside all day but I'll take it.
Peter: I've been watching United for over 60 years and the first half was the worst I have ever seen. A little better in the second half but no real threat. Even our second goal was apparently well offside.
Leicester fans
Jimmy: Leicester were by far the better team, taking the game to United and causing lots of problems... then early in the second half made lots of stupid substitutions which disrupted the team tactics and shape Irrespective of United winning with a clearly offside goal, bad decisions cost us a lucrative place in the next round. Let's hope the Foxes show the same desire and passion to win for the remainder of the season.
Mark: We were cruising against a poor Manchester United until Van Nistelrooy took off Thomas and Ndidi. Garnacho coming on made all the difference and our genius manager takes the left-back, who was doing fine, off instead of the right-back, who was getting skinned. And don't forget the obligatory offside goal in favour of United (it wasn't even close, so how did the linesman miss it from a dead ball?)
Nick: It was a difficult watch. Ruud van Nistelrooy set Leicester up with a possession-based style, looking for opportunities to open up. Without the players with the ability to keep possession or the quality to produce opportunities, wins will never be easy to come by.
