Now he is about to come across another Denmark international in a professional capacity following the capture of Anders Lindegaard.
Although Sir Alex Ferguson has signalled time on Edwin van der Sar's stellar career at the end of the season, from January, there will be more competition at United's Carrington training complex, which Amos admits is not always easy to deal with.
"Games in the first team don't come round too often when you are the number three 'keeper," said the Macclesfield-born youngster.
"There is only one position and we train a lot.
"Every year I set a target because you have got to keep yourself motivated.
"You also have to be patient because a goalkeeper's career is different.
"Edwin is still playing now. You have to look at him as an example when the temptation is to look at players your own age, who are involved a lot more."
Amos certainly intends to squeeze every drop of knowledge from Van der Sar while he still has the chance, even if he appreciates his own analogy might not go down well with the veteran Dutchman.
"It is a little bit like training with your dad," he laughed.
"I don't think he will appreciate that but I am chewing at his ear all the time, trying to get bits of advice.
"He is very open and he says what he thinks, which is just what you need."
