Big personalities undermined Three Lions' bid...
Muller, 20, grabbed a brace in last weekend's 4-1 second round victory after Fabio Capello's side went into the match as favourites. The Bayern Munich star is just one of a group of starlets - including Mesut Oezil, Sami Khedira and Manuel Neuer - who overshadowed the experienced performers in the Three Lions' ranks.
Speaking to the press in the build-up to the quarter-final clash with Argentina, Muller believed that too many egos and not enough will to win contrived to send England home.
"England have so many top stars in their squad, they'll always be a part and parcel of the international football scene," Mueller noted.
"There are so many alpha males in the squad and it is difficult to have so many alpha males and roll in the same direction but you don't only need chiefs, you also need Indians, those willing to do hard work - that maybe a problem with England that players aren't mentally prepared to go that extra mile for their team."
Capello has since hinted he will bring in a raft of youngsters to shake-up his underperforming squad, a move Mueller backed.
"I don't know how many youngsters England have got to put through but if there are any they will certainly raise the standard of the team," he said.
"You need to have a team that plays as a team and maybe younger players are more subservient and they do what they are required to do."
