The Saints played out a 3-3 draw with Chelsea away from home in the Premier League.
Despite getting a point, Hasenhuttl was not happy with the way his team had to use a different dressing room due to COVID-19 protocols.
Asked about the rooms by reporters, Hasenhuttl said: "They are too far away.
"We lose nearly three minutes when you go inside, then we have to come out earlier and it's not possible.
"You want to coach, you want to reorganise the team. You have a time and they are struggling to go in this quick."
