If Rieko wants to improve, he needs not look much further than George Bridge. Bridge just put simply, is a superior winger at present.
Hes hungry, hes always looking for work, he chases kicks like his life depends on it, and swallows every high ball that comes his way.
He does the simple things very well.
Sometimes when your star rises too fast you can become complacent and rest on your laurels. He needs to fight for his jersey, unfortunately his NPC game didnt show any signs of that.
