Arne Slot’s side is on the verge of claiming their 20th English league title after a 2-1 victory over West Ham at home on Sunday, with Van Dijk scoring the winning goal.
They are 13 points ahead of second-placed Arsenal with only six games remaining and could clinch the title next weekend if results go their way.
Van Dijk’s future is expected to be secured later this week, with the announcement of a two-year contract to match Mohamed Salah’s new deal.
Forward Federico Chiesa was the only outfield signing in last year’s post-season transfer window, but he has made few appearances, and Liverpool manager Arne Slot will be looking to strengthen.
“I believe Liverpool will be able to compete for titles in the coming years,” said Van Dijk, who led the team for the 100th time in the league against West Ham.
“Whatever happens in terms of players leaving and coming in, I believe it will be a big summer. I believe they intend to make it a big summer, so we all have to trust the board to do the right thing.
“I believe we can 100% improve. I believe we should not forget the Premier League’s quality, particularly this season. “It’s amazing how everyone can beat everyone.”
Liverpool would benefit from a pre-season, according to the 33-year-old Dutch international, as there will be no major international competitions this year.
“This year, there is a training camp and there is time for the team to work on what the manager wants and I think that will then improve the team,” he told reporters.
“I think a proper pre-season would definitely help the club in order to be even more consistent than we already have been.”
Van Dijk is poised to become only the second Liverpool captain to win the Premier League trophy, and he hopes to add to that record.
“Being successful with Liverpool, the culture of the club, everything that embodies Liverpool — that is just part of me,” said the Liverpool captain.
“I love the club, which is pretty obvious. I believe you can see that in the way I speak about the club and the way I work for the club, both on and off the pitch, and that will remain consistent.”
