Jurgen Klopp has had a excellent first summer transfer window for Liverpool after the acquisitions of Joel Matip, Loris Karius, and Sadio Mane, but his work is far from over.
They have already spent around £39 million, with Mane taking up £34m of that sum, and Klopp should be looking to spend more in order to bring the glory days back to Anfield following years of underachievement.
The German boss must continue to capitalise on his reputation within the game, and also Liverpool's rich history, in order to bring in new recruits who are perhaps skeptical of not playing in any European competition next season.

Despite having a positive transfer window so far, Klopp's work isn't finished, and here are three positions he must strengthen before the opening day trip to the Emirates Stadium.
Liverpool's best transfer so far has to be the signing of Cameroonian defender Joel Matip on a free from Schalke, but more defensive reinforcements are needed.

With Martin Skrtel on his way out, Dejan Lovren still needing to improve at Anfield, and Mamadou Sakho currently in a tough situation with UEFA over his anti-doping ban, Liverpool need to bring in another centre-back to join Matip.
There are many possible targets available, but finding the one that fits Liverpool's needs will be difficult.
Whether Klopp goes for someone young and upcoming, or someone with a bit of experience is still unknown, but looking at Liverpool's defence, the German manager would be better off signing someone who's ready for the first team straight away.
Alberto Moreno is a solid left-back in terms of attacking as his pace and on the ball ability is great, but he has shown inconsistencies throughout his time at Anfield, and his actual defensive abilities are not up to scratch.
Klopp must get a left-back to either put pressure on Moreno's position, or take over his position completely.
There are many targets available for the Reds, so losing out on one is not the end of the world, but making sure they actually acquire one that will both make themselves and Moreno better will be key.
Competition for places can often bring the best out of both players, and that is something Klopp should consider when searching for a new left-back. Not only could the new addition strengthen the side, but it could also bring the best out of Moreno.
There has been a lot of speculation that Joe Allen and Lucas are both on their way out of Anfield, and with the aging of James Milner, now is the ideal time for Klopp to bring in a young central midfielder for the future.
Like all of the Reds' transfers so far, Liverpool should be looking for someone who has played at a high level, but at same time, someone who can be moulded into what Klopp wants.
With players like Emre Can, Jordan Henderson, Philippe Coutinho, and Adam Lallana currently in the midfield group, this player will be able to learn from established and experienced midfielders who have played in the Premier League.
The key to a good transfer window is buying players who can strengthen your squad immediately, but also sign players with a view to the future, and a young and hungry midfielder could be ideal for Klopp this summer.
