This is weird. Shouldn't Firmino be out there scoring goals like madman in order to be a world class striker? No wonder he's shit. They could put Dele in and get them goals. Not to mention, as suggested further up, with Winks' physicality to bolster their midfield. This all sounds like just the prescription Klopp needs for a rebound. Yup!A big part of Firminos job is to make passes, drag defenders out of position, dropping back to get the ball so that Mane and Salah are able to get the ball in space behind defenders. Alli is terrible at all of that.
I am not sure there are two players much different in what they do and are good at than Dele and Firmino. Alli would be a terrible fit for Liverpool and Klopp.
