I recognise langer to the left, don't know about the picture to the right.
the argentina and the german reference I see too
stephen hendry is the most successful snooker player, the other two I googled (baseball and darts). some things they have in common:
all of them are commentators. in all three sports the main thing needed is a accurate and calm arm.
hendry has an MBE, the only tennis player I could think of having a mbe is sue barker - who also now is commentator/presenter at bbc.
the shoes are converse which probably leads to something. I cannot get anything from the lard (had to look it up plus I thought it was cotton)
also I think the burger refers to "hamburg" which could be where the match has taken place.
... still have to think a little bit more
