Tierney's a decent offensive weapon, has a pretty intelligent delivery but he's not touching Trent in that arena - nobody is in the PL. He's the most reliable creator in his position by far. I'd also argue that Robertson is a more reliable offensive weapon at this point - particularly when it comes to dribbling. Tierney attacks space really well though and I think he's probably a better defender than both. Liverpool's set-up protects their full-backs because their midfield goes through a **** ton of work defending laterally. Tierney for me does really well on 1v1s often and never looks outmatched - even against Adama Traore, who beats everybody on the dribble, I thought he did mostly well bar a couple brief moments.
