Yes, but what one could get, and what one is offered, because the individual is desperate to get their foot in the door, is sometimes not close to what is fair.
Eg he could get 1000/wk, but they offer 200, take it or go back home..then your agent have to rationalize in yuh head that it's ok if yuh making 1/5 everybody else salary, yuh still out playing them, and making more than if yuh was home, just hold on till next year, so yuh going thru the year as a foreigner, language barrier, no friends, some heckling & insults, no immediate friends,no Doubles, training and playing harder and better than everyone else, yet might make less...sometimes it might be difficult to concentrate...
So I hope if he manages a decent showing, the club treats him with the respect he deserves, and not use/abuse his talent.
