Tuchel has named his 35-man squad for the two friendlies against Uruguay and Japan in March as the likes of Harry Maguire and Kobbie Mainoo returned to the side.
This is the last squad that Tuchel will name before he decides his final squad for the tournament in the US, Canada and Mexico in the summer.
Why have Maguire and Mainoo returned?
Speaking first on Maguire and Mainoo, Tuchel revealed that Manchester United’s impressive form has allowed them a chance to break back into the England set up.
"Manchester United have had an outstanding run since Michael Carrick took charge, and Harry and Kobbie have been a big part of that.
"As I said, this is the last camp before the trip to the US, so it's also my final chance to get to know new players, to learn about them, and see how they fit in. Harry isn't a new player in an England shirt, of course, but he’s new to me in this camp.
"I want to observe how he interacts with other players, see him on the pitch, understand what he's capable of, and gather enough insight to make clear decisions."
Tuchel explains why Trent missed out
Former Liverpool and now Real Madrid star Trent Alexander-Arnold has been left out of the side in favour of Tino Livramento, Dan Burn and Lewis Hall all from Newcastle. Tuchel explained what was a tough decision.
"It's a tough decision, and Trent is a big name - a huge talent with an impressive career. I know what he can give us, but I've opted for others.
"We were very good in September, October, and November, and I know what Trent can offer. I've also faced challenges when he's played against my teams.
"The players in camp at right full-back must push to earn their spot on the plane to the World Cup."
Bellingham won't be risked
Finally, he touched upon Jude Bellingham who has not played for Real Madrid since February. Tuchel said he will not take risks with the midfielder ahead of the tournament where he will be one of the leaders in the side.
“The best case scenario is he gets some minutes against Japan”, Tuchel adds.
“I wanted Jude to be in camp, Jude wanted to be in camp and Real Madrid are happy for him to be in camp. We can provide team training for him, with Real on international break. All boxes are ticked.
“It's important to get expectations right - we will continue his progress and integration into team training. We will not take any risk regarding risk of re-injury. It's rare for him to have a muscle injury so we will be very careful.”
