A very high profile German player actually accused the actual German national team of being racist not long ago. Germany also has a much more significant problem with hooliganism at club level than there is in England. It almost doesn't exist in England anymore.
You can read the EU report in to racism against black people in Europe if you want. It finds that racism against black people is much more common in Germany than in it is in the UK by almost every measure, more verbal abuse, more physical attacks, more discrimination in access to housing and a more racist police force.

One thing is that true is that non-British people consume the UK media far more than than they do for any other country so what goes on in other countries goes under the radar a lot more. The big issue here for me is that these narratives are being used as a vehicle for bigotry against the English people at large but when you look deeper into the truth about racism in Europe the reality is a lot different. People accuse the English of an exceptionalist attitude but the irony is that many people are proving their own exceptionalist attitudes through this criticism.
Marcus Rashford's mural in Manchester was defaced with a racist slur after the game, since then its become somewhere for people to gather and cover the slur with messages of support for Marcus and the other black players that missed a penalty. I'd prefer to see this as a metaphor for where we are now. A toxic minority that will be drowned out.
Again I'll say that all this doesn't mean that we don't have significant problems in England with racism. We still have a long way to go.
