Jack Grealish labelled the abuse that was directed at him by the England supporters as ridiculous.
England beat the 10-manIvory Coast by three goals at Wembley, with the last one coming from Tyrone Mings, who scored with the final touch of the game.
There was a big talking point before the start of the game when the name of Maguire was booed.
The Manchester United captain is enduring a difficult season with his club but he was called a joke by the England manager.
I thought the reception was a joke. He told Sky Sports that it was an absolute joke. I don't understand it.

We are either all in this together or not. He is in an England shirt and you should support him no matter what, but when he is playing at the level he has, it should be total commitment behind him. I don't understand it.
He stepped out from the back for the first goal and was involved in the second goal. The team is united. He is the top player and will come through difficult moments.
They are real England fans. I don't know if it's social media, players that have played previously that are influencing opinion. He is in an England shirt despite his club situation.
I remember a time when some players were booed in England shirts. I have never been able to get it. People play better. Fans should support their team.

During the match, the name of the defender was sung by the crowd, but he insisted that England will need him at his best if they are to do well in the tournament.
It becomes a mob mentality. There is a hardcore section of fans playing his song at one end of the ground. I am aware that it is not everybody. We are either all in it together or we are not.
Don't think for a second that the other players won't be thinking about that one day. That has been a problem with playing for England. The players have thought about whether or not they should go because the crowd will turn on them. It happened with John Barnes, and it happened with Ashley Cole. And now Harry. They are all outstanding players.
We need Harry to play well to have a chance. We are not going to win the World Cup with players with more than one cap. That has not happened in the history of the game. We need our experienced players to play well.
He is the best centre back at his club. It is ludicrous. Every time he steps onto a football field, his actions are analysed to death. I don't recall a player having that sort of spotlight on him.
Jack Grealish said the team didn't like it.
Grealish said it was ridiculous and he was brilliant. Our first two goals, first one he drove out with the ball, second one he drove a bit and passed the ball to Ollie. Not every centre-back has those qualities.
It's ridiculous for him to get booed because he's been a fantastic servant for his country. It was something the team did not like. Harry is a strong-minded person. His performance tonight will make him a better person. It will make him want to go on. It is not nice to hear but you have a job to do.
We had a great relationship with the supporters last year at the Euros and we need to keep that going into the World Cup.
With the draw for the World Cup coming on Friday, England will be in a good position to win the trophy.
He says that his team will have to learn from their past mistakes, including an error in the friendly with the Ivory Coast.
We are one of the teams that can win the World Cup. We have to keep pushing because it is an exciting group of players.
Even at 2-0 we give a poor foul away and a free-kick they should score from. You can not afford those things. Throughout the week, I have been really pleased.
While reflecting on the possibility of going to the World Cup with that possibility, he said he has different feelings towards the competition compared to the previous World Cup.
He said that they have more evidence of results and expectations. That is very exciting.
What are the key dates and kick-off times for the World Cup finals in England?
