Former Strasbourg boss Rosenior said the memes affect his family but he is not troubled by them because he expected the reaction from the moment he took the Chelsea job.
Rosenior was a surprise appointment following Enzo Maresca’s departure in January.
Since joining Chelsea, Rosenior has become just the second English manager to win his first four Premier League matches.
He also led Chelsea to the last 16 of the Champions League following a 3-2 win at Napoli in January.
“The reason I know is because I’ve got teenage children,” Rosenior said of the internet comments.
“They’re on social media. It affects them, it affects my parents and my family. But I knew walking in to this job it was going to happen. It’s normal.
“When you’re prepared for it, it makes you smile. I’m a confident person. If you’re affected by things like that, you shouldn’t be in this job.”
The Blues sit fifth in the Premier League – one point behind fourth-placed Manchester United – and host 16th-placed Leeds on Tuesday.
