For sure he can contribute a lot as already shown this season, but his weaknesses are being absorbed by the team on a winning run.
Is that acceptable? some appear to be ok with that as they clearly think this is a drop in form
Think there are more reasons to think that it is a drop in form than that it is a tendency of declining. Sterling turned 26 two months ago. Same as Bernardo. Bernardo had a longish dip in form and many on here were writing him off. He had 0 goals and 0 assists 3 months ago. Sure, techically he has been better and more reliable than Sterling but he was utterly unproductive. And look at him now. How can one be firmly convinced that Sterling has peaked when Bernardo was in a worse situation and has turned it around to the extent that he may be more important to the team than Kevin?
