Wow. I did not see this coming.
His quite literally what I saw as the perfect no.6 in Klopp's team. I remember discussing it over the last 12 months several times but didn't see any links and had resigned from the idea thinking he'd go to Man Utd. One of the best athletes going around, he can play as a no.6, RB, RWB, defensive winger or midfield runner in a no.8 role. He great in the air, gets stuck and is solid on the ball. Not Alonso on the ball but a good range of passing and can dribble and score goals.
I think he provides a range of tactical possibilities. While Oxlade is out he could cover the right side protecting A.Arnold and Salah, and bomb forward (he had a goal in him). He obviously can be our no.6 and I think will be our starter there long term IMO. It's a question of if that's the best role for him in the immediate future or if he should play further forward until Oxlade returns.
