I don't think he'll be just good, I think he'll will be great.
There are as you point out obvious areas of concern but he is still a young lad trying to find his feet and settle into the team. And as with every other player in the squad he's not had the best of Seasons so far but I am certain that Klopp is going to steady the ship now and create a healthier environment for our players in general and this will help our young players in particularly.
Ibe for me has got more or less everything you'd want in an attacking player - technique, strength, audacity, power, pace, eye for goal (this will be evident soon enough I hope) and a good shot. I even believe he's better in the defensive aspects of the game compared to Sterling and in the longer run my money will be on Ibe to be the better of the two in direct comparison.
I also think he has a great mentality, and though he has certainly faced an uphill task this Season mostly, I have him pegged down as one who is actually going to learn from this and use it to improve further.
