If you think that about Willian, then why compare him with Pulisic when no one was even talking about him? Why not just get straight to the point and say Willian was good because he did A, B, C etc? Why even compare? I don't even think anyone has said Pulisic has been great. He's showed glimpses but he hasn't been great yeah. But he's only 20, he joined a new team - a team that's undergoing transition - and has come to a new league. People are willing to give him to time to adapt and get better.
Seriously, if people are gonna come here and blow their trumpet about Willian - whether by comparing him to someone else or not - after one decent performance - one decent performance in a glut of inconsistent performances - then god help us all.
