If he's up to it, i'd even think about having him on the bench tomorrow. His attitude, work rate his constant desire to play it up the pitch and his creativity could be useful against Liverpool. Especially at a place like Wembley where we have a habit of getting frustrated and going missing.
I think the longer Lamela has been out the more people have invented things he does.
He's rarely ever replicated the style or skill he showed at Roma for us. He's nowhere near displacing Eriksen or Dele behide/alongside Kane. He's not even 1st choice to fill in, being behind Son.
If he starts game's regularly he's going to have to be playing like De Bruyne on steroids.
I’m sure what we'll see is lots of elbows and digs, lots of running. Some goals occasionally and some assists occasionally.
