The Reds finished in fourth place in the Premier League table last term to secure their continued participation in the Champions League ahead of the new season.
Liverpool FC reached the Champions League final last season after Klopp’s side managed to beat Portuguese outfit FC Porto, Premier League title holders Manchester City and Serie A giants AS Roma in the knockout stage to reach the showpiece.
However, the Reds lost 3-1 to La Liga giants Real Madrid in the Champions League final in Kiev last season following goals from Karim Benzema and Gareth Bale.
Liverpool FC have already signed Brazil international Fabinho in a £39m deal from Ligue 1 side AS Monaco earlier this month, while Guinea international Naby Keita is set to link up with the Reds from Bundesliga side RB Leipzig.
Former Reds star Alonso explained what Liverpool FC need to address in their summer transfer window.
“I think they need to not just have a ‘short’ team. Not 14 players – you need to list 20, 22 players to be able to cope with so many games,” Alonso told the Daily Mirror.
“Each game, each point is so important so you need to have the whole squad connected, ready to perform at the highest level, but with the principles and the idea very clear. That can’t change from game to game.
“For me the important thing is the team. The team is already built. After, for sure you need to bring new players, you need to add new, good things, but that doesn’t disturb what they have already been doing.”
Liverpool FC haven’t won the Premier League title but finished in second place in 2002, 2009 and 2014.
The Reds appointed Klopp as their new manager to replace Brendan Rodgers back in October 2015.
