Sunderland are still in both cup competitions, and a rearranged league fixture is just what Poyet does not want.
Sunderland - third bottom in the Premier League - face Southampton in the FA Cup this weekend.
Gus Poyet: "The fixture position is the difficult part.
"We will have a lot of fixtures to play in a shorter amount of time now, because of our success in the cups.
"It will be difficult for us, and I can't imagine what it will be like for Manchester City, who are still in the Champions League and the FA Cup.
"We came across on Tuesday and prepared as normal. We had a meeting (on Wednesday morning) and set off for the game as usual. But it was very difficult to get to the ground.
"A journey that would normally take about 25 minutes took more than 40. It's true that we saw a few incidents outside, there were a few panels coming down towards our bus.
"Of course we were ready to play, and we wanted to play. But we have nothing to complain about.
"You don't know what is going to happen, but we need to be honest. It was a strong decision by the police, and we have to agree with that."
