Keita became the club's record buy when the Reds agreed to a €60 million transfer a year ago, but to the deal's unique structrue, the Guinean only arrived in the summer of 2018 to bolster their midfield.
"But Liverpool have had to change there, because there would be no belief in Liverpool winning or challenging for the league with the two goalkeepers they had".
Liverpool have made significant strides in the market this summer as Klopp has moved to not only address their lack of strength in depth, but to also help beef things up at the back.
"Yes, they finished second last season but with a very healthy points total", he said when asked if people were jumping the gun on leaving United out of the equation.
"Joel, we'll have to see", Klopp said, according to the Liverpool Echo.
After such an early flurry of action, the goals dried up temporarily. He had a good World Cup and he will create competition for places.
"He had to learn kind of a new position for him. I don't know how we will do it".
"I think the first season he won two trophies, yes not the Premier League or Champions League but it's very hard to win trophies with that top six so competitive, so to win two trophies in his first season".
"Hendo for sure was involved in the first goal with a press ball that he didn't win".
"He can still play as the eight or we could play some games with a double six, Fabinho could play the eight or whatever, that's all possible", Klopp stated as he hinted at a flexible formation for the 2018/19 season.
Despite opening their Premier League campaign against West Ham on Sunday, Jurgen Klopp named a strong team and was rewarded by seeing key players get valuable game time.
While City start as title favourites, Liverpool know they are capable of outgunning Guardiola's side - they beat them 4-3 in the league at Anfield in January before a 3-0 victory in the Champions League quarter-final, first leg.
