Not premature because my opinion of him is based mostly on his performances in France. He can be effective - at a certain level - surely, but he's not an exceptional player like Morata for example.
Little premature to say Morata is exceptional, he's not been posting exceptional numbers. I like his determination and his style, has good feet and an aerial presence, but his contribution is little different to Giroud. His top level is probably higher. Lacazette looked better when Alexis wasn't in the side due to how he tends to put his foot on the ball and slow the play, reduce the space Lacazette has to run in behind and therefore less impact. He's probably better against bigger teams, somewhere where Walcott's one footedness and Giroud's mobility caused problems.
