The Belgian kicked off his second stint at the club in perfect fashion on Sunday by scoring in the Blues’ 2-0 win against Arsenal at the Emirates.
Tuchel played the likes of Kai Havertz and Timo Werner in central positions last season but the German wanted a more physical presence up front that could link up attacks and bring the side’s midfield into play.
Lukaku demonstrated that in the build-up to his goal just 15 minutes into the game in north London and his play with back to goal was exemplary throughout at the Emirates.
Tuchel admits he’s delighted with Lukaku’s start and says his ability with his back to goal means the side can now be ‘very direct’ in matches.
‘I am very happy with how he has integrated already,’ said Tuchel.
‘He is a very smart guy. He likes to be in the group and he is a very democratic leader because he talks to everybody.
‘He’s very friendly, very humble and totally competitive. He gives something to our game that we did not have so much [last season] like to protect balls and play very direct up front and to the last line.
‘You cannot start better than the goal but he almost scored a second one here but it was a big save from Bernd Leno and he assisted some half chances. It was a good start but we have to improve from here.
‘I didn’t expect too much [from Lukaku] because I wanted to be open to see his strengths and his capability to adapt and to link up between Kai, Mason and him. This is what he did very good, The guys like to play with one another and from now on we can go into details.’
