It isn't. Sometimes you need to go back to basics in order to achieve your goals in life. He seems to be determined to get back into the first team fold and playing a few games in the U23's to gain confidence isn't going to hurt... If you watched the Chelsea game you could see that the U23 level is far too easy for him and he was head and shoulders above both teams players. Now, he needs to show that same confidence in training so he starts making the first team squad on matchdays.Why is Nelson playing for the U-23's? His development is just wasting away.
