First of all, unless I’m corrected, I can’t at all recall Sterling ever playing right-back.
And even so, that has to have been a ‘once in a blue moon’.
The fact of the matter in which unfortunately fell on his shoulders due to the heights of 2013/14 was the pressure as an offset striker after losing Suarez in the Summer of 14, and Sturridge being out.
Steven Gerrard wasn’t starting as many games, Phillipe Coutinho was a little out of sorts and Martin Skrtel was occuppied in his own matters at the heart of the a new defence.
Sterling felt tired, disjointed, and not quite the same as the previous season so he wanted out.
We can get that and have accepted and moved on. His agent is talking nonsense and these feeble excuses are just unnecessary.
