If he keeps impressing, who knows.
He was probably bought for the U23s with a view for the long term
But in pre season he might have changed Klopps mind and maybe he could see him challenging for a spot. We don't know.
I personally think he's capable of doing so.
Firmino is clearly the main man upfront for us. After that, I feel the spot is up for grabs to be his back up. Forget reputations, if he's playing better than Origi or Sturridge, he should be that man. If he isn't then he can play for the U23s. But I wouldn't bet against him forcing his way into contention. If he keeps impressing, then that will happen.
Harry Kane wasn't first choice for Spurs a few seasons ago. But he kept scoring in the Europa 'B' team and he forced a chance in the first team and hasn't looked back. If he keeps scoring and impressing, he'll get chances and if he grabs them that can only be good for us.
