Reece James is the most versatile Chelsea defender.
The English defender has missed two months of the 2021/22 season due to a hamstring injury.
But since his return, he has been deployed in the right centre-back position than his customary right wing-back role.
The 22-year-old is expected to be at the heart of Chelsea’s defence against Manchester United on Thursday night as both Rudiger and Christensen are out with injuries.
Tuchel said: ‘I would love to have two of Reece James, that would solve the problem, it’s like 50% towards wing-back and 45% towards the back three.
‘It depends a little bit on how the opponent plays against us. Do we expect a lot of possession, how is their structure for their offensive transition.
‘For this it can sometimes be helpful for Reece to play in the back three and be the first guy to cover in the transition and to not be involved in the attack. We have his speed and physicality in the protection of the opponents counter-attack.
‘I’m a bit more into that his very best position is the wing-back position where he is perhaps even more decisive, more useful but it is more demanding.’
