I have to say Im somewhat mystified by people who think Ibe is well on his way to being a better player than Sterling. From about the age of 17 it was obvious to anybody who cared to look that Sterling was going to be a top class player. Ibe will be 20 this year and hes still not cemented his position as a first team player yet, obviously player mature at different rates but Ibe has to improve a hell of a lot this season if hes going to get to Sterlings level. The major criticisms of Sterlings game was that he was a poor finisher and his decision making is suspect, however he easily scored more goals in the Premiership than Ibe did in the Championship. As far as I can see Origi is far more likely to reach the level Sterling did based on what we have seen so far
Ibe was scoring at a better clip at Derby than Sterling did with us. If you have watched Ibe progress through the youth ranks and on loan, such as @gkmacca, @peterhague, and @studsup (I have thanks to their highlights over the years), then you would know Ibe has always looked the star player in the making. He scored bucket loads at youth level. I think if you go back you'll see that Raheem scored 2 in his first 19 appearances from an attacking position, while Ibe had to play WB mostly. If Ibe gets to play LWF, he will score goals - simple. Just be patient and let him develop - it will most likely all click at once at this level with him.
