Maybe Coutinho..
Maybe Rakitic also. Why Rakitic? Because he is too slow for the midfield, he is not very physical (like Vidal) nor very technical (like Arthur). To be fair, I wasn't focusing on him all match, but I remember that the most dangerous action of Liverpool came from a bad clearance of Rakitic at the end of the game (maybe tired?); it was a normal aerial ball, he cleared it badly, and then liverpool recovered it soon and the ball came to Salah in front of our goalie but he hit the post ! (we were lucky)
Also in the dangerous shot of Milner saved by Stegen, I see that Rakitic was responsible, because he arrived too late, didn't track Milner quickly. Is the old Milner quicker than Rakitic ? We shouldn't afford to make that kind of Mistakes in Anfield. Every ball, every movement counts !
