Markus, on the other hand... I heard he goes 'round bars and town bragging about being Mikael's brother.
This sounds utter ********. Markus propably does have a normal party side to him (he has been in some photos in Helsinki night life), but by no way could he be "bragging about being Mikael's brother". And why would he. It's not like a hockey player wants only his brother to succeed. Markus has a healthy self confidence, and some people in Finland don't like it. Rumours like this shouldn't be thrown around like they were confirmed facts. If there are several youtube videos uploaded where Markus is saying "hey guys, I'm Mikael's brother, deal with it" in several different bars I'll maybe learn towards believeing it. Until that happens it's either him joking, or some sad person just making things up.
Just think it through how impossible it is to be true. Markus wants a name for himself as a hockey player. Not as a hockey players brother.
