The team's performance was disappointing, with a 1-0 win against Andorra in Barcelona followed by a friendly defeat to Senegal at the City Ground.
Tuchel acknowledged the efforts of his predecessor, Gareth Southgate, and current team manager, Lee Carsley, in trying to bring talented players together.
However, Tuchel emphasized the need for individual players to put the team's interests ahead of their own, and for the team to find the right balance and chemistry.
He noted that the team's performance will be crucial in the coming months, particularly as the World Cup approaches.
