The Reds have drawn their last two matches - at home to Everton and West Bromwich Albion - and visit the south coast this weekend for their third Premier League fixture in the space of a week.
However, Robertson insists Jürgen Klopp will have the team re-energised for the trip to the Vitality Stadium.
Speaking as a special guest on this week's edition of LFCTV's 'LFC Later', the Scotland international said: "If there is anybody that is going to get us up and going again it is him.
"We have had two draws at home; it’s disappointing when we look to take maximum points. But the fixtures are relentless and we have another game on Sunday.
“We have got no time to hesitate, so we need to try and get focused on that and get back to winning ways.”
Robertson has had to bide his time at Anfield following his summer transfer from Hull City but has started Liverpool's last three Premier League fixtures and is keen to build on that foundation.
“From the start of the season I have had to be patient,” the 23-year-old said. “I’ve maybe not played as many games as I would have liked.
“Unfortunately Alberto [Moreno] got injured - and hopefully he gets back as quick as he can - but in the meantime hopefully I can take my chance and get some games under my belt and then just keep building on my confidence.”
'LFC Later' aired at 9pm GMT Thursday and will be repeated regularly on LFCTV throughout the week. The episode, which also featured a guest appearance from Gary McAllister, will also be available on demand on LFCTV GO.
