Neymar has primarily operated from the left since joining PSG from Barcelona in August 2017 in a world-record €222m transfer.
But this season Tuchel has at times deployed him in a central playmaking role away from his favoured position.
The Brazil international started on the wing against Rennes on Sunday but was shifted to the middle in the second half and played a key role in the Thomas Meunier and Eric Maxim Choupo-Moting's goal - with the latter assuming the left-sided role.
"Of course he likes to be there and we like to have him in the number 10 position because he is involved in every attack, not only from the left," Tuchel told the press, as quoted by AS.
"He has the chance to be a bit more free and be in the centre of the game and we have the chance to involve him in every attack we make.
"If you involve Neymar in your attacks, there's a high possibility that you create chances.
"This is how I think about players, so what can we get from them and what do we want from them and this is why it's a good option to play with Ney in the centre."
