Manchester City boss Pep Guardiola feels travel is affecting his players.
Guardiola was commenting after defeat at Tottenham in London last night.
He said, "Sometimes it doesn't work, but I can't complain too much.
"When you win the Premier League four times in five years, we cannot complain too much about what we have done and how we have done it.
"We try to continue and improve things. It will help us in the future.
"Now we have to go back to Manchester. Going to London is like going to Northern Europe. It takes four hours and 20 minutes to get to the hotel.
"It is so tiring to come to London. We need to get back to Manchester and prepare for the match against Aston Villa."
