I don't mind Elmo, I had question marks over his defending when he joined but he's improved since he's bene here, far fewer silly mistakes now. However he's 33, if we're moving on one of the right backs I don't think he offers anything more than Guilbert who is 7-8 years younger and coming towards his prime rather than at the end of it. If it's a financial decision then that's fair enough I guess but in terms of squad development I'd rather keep Freddie.
That said I would be against keeping both for a year and having Elmo as an older head covering 3-4 different positions.
