A few more seasons here he would be ready for the Barca challenge now.
He was 1 rung below world class in my opinion purely based on never putting it together for 1 totally brilliant full season.
He's struggling and my guess is his confidence is low and he doesn't have the respect of his team mates that say Suarez could command based on reputation.
PSG next perhaps?
Think he moved a season or two too early.
Not that it matters now, damage is done,
but all the tactical talk in his last season at LFC was dropping him into the midfield 3.
A year or two of that and he'd have been perfect for Barca but instead Barca had to jump early
and Coutinho didn't have that extra season working behind the front 3.
