Liverpool manager Jurgen Klopp hopes his team are on track for a Premier League title challenge after their highly rated additions.
Klopp has already strengthened his squad with the signings of Naby Keita, Fabinho and Xherdan Shaqiri, while Roma goalkeeper Alisson is reportedly close to making a move to Anfield.
Mohamed Salah and Roberto Firmino have re-signed with the club, seeing speculation over their futures – particularly the former's – ease.
"I am not 100 per cent sure but maybe it is the first year we don't sell a key player," the German told UK newspapers.
"There was always a lot of change, but in both directions. Now it is more in one direction. That is clear. Big teams, successful teams, if you don't buy it you have to build it.
"That means stay together, bring additions in and make the next step."
"The team and squad is in a really good moment," he said.
"We had the situation last season where we had 12 [first-team] players [fit]. They know we need the depth in the squad. They know it. It is not like they say, 'Bring in another midfielder? Why? We are all still here'.
"But they know we need the quality and they know that if we win something here then we will win it with 25 players. That is exactly how we feel."
