Thomas Tuchel said Jarell Quansah is fully fit and could start at right-back for England against Mexico on Sunday, giving England a fresh option on the eve of a World Cup last-16 tie. The defender trained after the ankle injury he picked up a week ago against Panama, and Tuchel said he is now fully available.
That is the reason Quansah’s name is being searched now. England are one day from a knockout match in Mexico City, and the right side of the back line is the spot that could still change before Sunday’s 6pm kick-off. Tuchel has already declared Declan Rice fit and expects him to start alongside Elliot Anderson in midfield, which means the main selection debate is shifting to the defensive line rather than the middle of the pitch.
Quansah’s return matters because Tuchel did not frame him as a player who will merely make up the numbers. He said the defender could start at right-back over Djed Spence, a clear sign that England may go into one of the biggest matches of the tournament with a changed shape on that side. For a team facing Mexico in a knockout setting, that is not a minor adjustment. It is the kind that can alter how England build from the back and how quickly they settle into the game.
The question that remains is Reece James. He missed team training on Saturday afternoon and instead followed a personalised programme while recovering from a hamstring injury. Tuchel said James could maybe make it on the bench, but only after a last assessment from the doctors and a medical opinion. England’s one-hour training session on Saturday afternoon offered no public answer, which leaves the right-back picture open even as Quansah has moved into the frame.
Mexico City adds another layer. Tuchel said he does not expect hostility, even though the stadium should be full of support for the home nation, and he noted that around 100 riot police are guarding the England hotel to the west of the city centre. The altitude, at 7,220 feet above sea level, is part of the challenge too, but Tuchel tried to keep the mood calm and said he did not want to talk about problems that do not exist. England will need that composure if the doctors clear James late and Tuchel has to choose between a player still working back from a hamstring problem and Quansah, who is already ready to go.
By Sunday afternoon, the decision should be plain enough. Quansah is available now, James is not yet certain, and England’s first knockout night may turn on a medical check as much as a tactical one.
