Brentford boss Thomas Frank says his No2 Brian Riemer has the ability to be a top line manager.
Riemer moved to the Bees from FC Copenhagen.
Frank said, "I think Brian is an insanely good coach and maybe one of those who does not run so much with the headlines, because he is of course an assistant coach, but he is a huge part of our success over here. He has a huge, huge stock in it.
"He is a really good trainer on the training field with many and good details on everything that needs to be trained. He is insanely good at developing players and for one-on-one interaction on and off the field.
"He has the main responsibility for the defensive in relation to training and evaluation of the team and does a top job there. When talking about coaches abroad, he counts. It's not just me as the so-called chief. It's great that we have more Danish coaches abroad."
