Pep Guardiola says Manchester City's players are still not fit ahead of facing Wolves, their third Premier League game of the season due to the effects of a shortened pre-season because of the World Cup in Russia.
"The problem is that now - while we are not far away - we are still not fit," said Guardiola.
"We see how much the players spend for regeneration after the game. Normally it's quicker - one or two days - now they need more time.
"It's because we didn't make a pre-season. When we arrive, immediately after three-four days we played the Community Shield and Arsenal.
"Some players need much more time to win power, strength. The players complain about muscular problems - that's why Claudio got out, Kevin. This week Fernandinho had problems with regeneration after the game.
"But it's normal, we demand a lot and still we are not in the best condition. Hopefully after the international break the team can be better and better."
