Haha, sold two of your best players there. Wellens actually has a lot of pace on the game and is rated better than Campbell
Whereas, Flannery is just your average player at Loose Forward, cheap, does the job and scores lots of tries.
Alliance is basically the under 19s. The bigger the development bar is the better than the player will become. So, if it states next to their development bar that their rating will be National, International, then you might as well play them every week.
Can accept your dream teams and rep teams by going to manager, then click profile and click the job you wish to accept, then go to the bottom left and click accept. No need to reject jobs, as they dissappear once you have accepted your job.
