Derby boss Wayne Rooney says Manchester United captain Harry Maguire won't be bothered being jeered by England fans.
Maguire was jeered by the home crowd before and during England's friendly against Ivory Coast on Tuesday, having kept his place in the team despite underperforming for Manchester United this season.
Rooney told The Sun: "I've been there. It's never nice when you're booed by your own fans.
"Harry's a top lad and a top professional. I know Harry personally. I spoke to him not long ago and he's a strong character, he's strong-minded.
"I've spoken to him a few times as a friend and we've had a general chat, but I'm not his mentor.
"I'm sure the people who were booing him are not real England fans. Because as a fan, you go there to get behind the team.
"I don't think any England fans are concerned about his form for United as long as he's doing well for England."
