I like what Tuchel is thinking there. One shouldn't be happy with the arrival of goal machine like Lukaku and we have yet to see how he performs in PL. We have yet to see if arrival of Lukaku will settle their unavailability of a goal scoring striker for sure. Last year Chelsea under him did well but most of the points were lost under Lampard. Now Tuchel has nothing binding him down to keep them out of the race. I think they have good chance to win PL in this season and it is impressive to see that he are also thinking highly of his opponents and not undermining them.
Lampard did his job well in first half of last season. He only got troubles in the second half and he was fired, then Tuchel came and revived Chelsea, brought them to top 4 and even won the Champions League. It is the second Champions League title in history of Chelsea. Tuchel already has a spot in Chelsea's Hall of Fame.
With Lukaku, Tuchel will be able to use Werner in another position, at two sides and I think Werner will be more dangerous in swings, not in central area as a striker. He has good ability to break down defense system of opponent. Tuchel needs it and goals can be from other sources, Lukaku or other midfielders of Chelsea.
