“It’s clear bullying,” Slovenia FifPro member Dejan Stefanovic told the BBC.
“In Slovenia, we would have indicted Mourinho and asked for the highest penalty – three years in prison.”
Speaking to BBC World Service Sport, lawyer Stefanovic, who is also president of the Slovenian Footballers and Sportsmen Union added: “This is clearly meant to discourage Bastian.
“Mourinho is setting a bad example. I would take it to the ordinary court. In our case, the penal code is quite clear. If there is bullying and harassment, there’s a prison sanction, a maximum of three years in prison.
“Schweinsteiger should turn to the Professional Footballers’ Association and he should file a complaint and I would also seek penalty for Mourinho.
“All the players of the first team have to train with the coaches of the first team at the same place, at the same time as all other team-mates, that’s something that should be applied to each and every club and should be written within Fifa regulations.”
BBC Sport has contacted United about Stefanovic’s claim but is yet to receive a reply.
Schweinsteiger’s brother Toby, assistant manager of Bayern Munich’s Under-17s team sent a tweet on the evening of the Galatasaray match which said merely “no respect”.
Bayern Munich president Karl-Heinz Rummenigge, another former Germany captain, said in German publication Bild: “One or two players are going to think long and hard in future about whether they want to go to such a club.”
