Manchester City boss Pep Guardiola wants up to six substitutes to be used in matches.

Guardiola says increasing the number of substitutes available would lead to fewer injuries and more open games.

"Everything would be better," he said.

A decision on whether to expand the World Cup will be made in January and any change would be unlikely to take effect before 2026, but Guardiola is unconvinced by the idea.

"This kind of thing is impossible because we are going to finish [the season], then after one week the World Cup then after three weeks we go to the pre-season, we go to China, the States, Australia," he said.

"You play against Milan, Juventus, Madrid and you have to win. People demand you have to play good [with] no preparation. Then you come back and it's 11 months again and it's the European Cup."
