Well he's not literally Roar's Gui because they usually play different positions and are different types of players.
Gui is an aging, foreign attacking midfielder who has played his best football already.
Broich is an aging, foreign attacking midfielder who has played his best football already.
To make things more interesting
Fahid Ben Khalfallah is also an aging, foreign attacking midfielder who has played his best football already and he signed for the Roar!
Broich and Khalfallah are more wingers though. For the position that Gui plays speed and stamina isn't as necessary as the other two.
Gui is also 4 and 5 years younger than the other two.
