Ancelotti keen to use Chelsea bench in Seattle
"For sure we will do substitutions," Ancelotti told Chelsea TV, having ruled out his recently-returned African contingent from the Seattle game.
"The African players...have to improve the training and physical condition, but after (that) the Africans will play.
"The first match against Seattle we change, we change, we change."
Midfielders Joe Cole and new signing Yuri Zhirkov did not make the trip, Cole following knee surgery while the Russian will join the tour at a later stage.
Other new signings Ross Turnbull and Daniel Sturridge are in line for their club debuts and trained with the rest of the squad at the training facilities of NFL team the Seattle Seahawks, where Terry, Didier Drogba and Michael Ballack received some pointers on gridiron from quarterback Matt Hasselbeck.
"They are all in good condition," Ancelotti said of his squad.
"We want to improve our physical condition and quality of play. This game we will try something different and this is our objective.
"The games are the most important training. We will have to improve the condition, quality of the play, find the concentration to prepare a game, and for this we arrive at the right moment."
