Both have overcome serious knee injuries to play at the highest level with many arguing that Shearer is still the most complete striking package in the Premiership.
We'll be able to judge that for ourselves when Shearer leads Newcastle United's attack in Wednesday night's cracker at the Lane.
"Shearer looks a strong as ever," said Steffen. "Players like him and myself will always come back after injuries because we know what we have to do.
"That's what he did. He was out for a long time with his knee injury and although Newcastle played well without him, when he came back they were a different team.
"I don't know him personally but on the pitch, he is there when you need him, in bad situations or when you are struggling as a team. He can change games and we will have to watch him carefully."
Steffen Freund admits he knows nothing about Alan Shearer the person - but they do share one particular professional experience.
