Mourinho fears his team are at another disadvantage with Saturday's match kicking off at 5.30pm, allowing it to be screened on Sky Sports.
He told Chelsea TV: "It is harder for them [the players] than for me, I sit on the bench. This week is going to be even worse [than last].
"[The players are travelling to] South Africa, United States, Portugal for others. Okay, some England players will be at Wembley but it is still a match on Wednesday and we play on Saturday, which I don't understand.
"We don't play Champions League next week and I don't understand why we don't play on Sunday. I want somebody to tell me that we play Saturday because of this and this and this but nobody tells me.
"Clearly, I don't understand why we don't play Tottenham on Sunday. Tottenham have a Europa League match on the [following] Thursday so they don't need to play on Saturday. They also have a few players in the national teams, not just us."
