Hakan is contributing very little, it's not just that he is not scoring. He made a couple decent moves, but he also wasted a very easy 4 vs 2 counter, he can't put in a proper cross or set piece, and goes from very energetic to completely lethargic.
IMO the way we play, we could have used a inside forward type there for a while -- André Silva for example. Someone who can basically finish chances in the far post and create space for Rodriguez and now Paquetá, and run like crazy for 90 minutes.
Borini is poor but above all very clumsy, which IMO makes him look worse than he is, and some fans see those kinds of players as particularly useless. I don't think Borini is starting material, don't get me wrong, and I'd prefer Castillejo, but right now Hakan really has got on my nerves in that position, and I see him as one of the main reasons we can't seem to create good chances. I'm happy to see him in other roles though.
