Pretty much everything is looking bright for Jurgen Klopp and his side. Four wins in a row in all competitions, scoring thirteen goals and a Europa League quarter-final to come, but the Liverpool boss still needs to add quality to his squad this summer.
The Reds play Villareal on Thursday, but will be without captain Jordan Henderson, Emre Can, and Divock Origi through injury, while Mamadou Sakho will also miss out as he is being investigated by UEFA for anti-doping claims.
Here are four positions that Liverpool should look to strengthen this summer.

Simon Mignolet hasn't done much wrong recently, but it will be hard for Liverpool supporters to forgive his horrendous mistakes over the last three seasons.
While the Belgian keeper hasn't made many high profile mistakes in 2016, his distribution is still a problem. Klopp likes his side to build attacks from the back and retain possession of the ball, but Mignolet's kicks are often misplaced.
This often results in a counter-attacking opportunity for the Reds' opponents. His aerial ability is also still questionable, and although he hasn't dropped the ball recently, he now rarely punches or claims the ball, and therefore pushing the responsibility onto his defenders.
In The Telegraph, the former Sunderland keeper was in the Premier League's worst XI this season. With the keeper saving just 60% of the shots he's faced - the second-worst save percentage in the league.
As well as making three errors leading to opposition goals against Norwich, West Brom and Sunderland. If he didn't make those mistakes the Merseyside club would be a point off fourth with a game in hand.
Of course, it's not entirely Mignolet's fault for Liverpool's league position, but his nervy moments spread to the rest of the defence. Imagine where the Reds would be if Klopp had David De Gea in goal.
Left back is an area in which the opposition persistently target when they face Klopp's side. The reason being that the Reds don't really have one when Alberto Moreno plays.
The Spaniard seems to bomb forward and neglect his defensive duties, leaving a gaping hole for his opponents to exploit.
He isn't even prolific in attack either, contributing two assists in two seasons.
Liverpool legend Jamie Carragher agrees that Klopp should sell Alberto Moreno this summer.
After the Red's Capital One Cup final defeat, he was quoted by The Liverpool Echo saying: “The left-back has to come out of the team. This is not a one-off today in terms of the goal.
“Flanagan played left-back when they nearly won the league. He can't be worse than him."
Jon Flanagan would be a good deputy, but he will need to cover Nathaniel Clyne at right back. Cologne defender Jonas Hector has reportedly been a target for The Reds.
Another position that should have been enhanced in the summer is defensive midfield. Emre Can has performed excellently in that role, but because the German has so much more to offer going forward he should be allowed to attack more.
Lucas Leiva can't play well every week and is often careless with the ball and makes rash tackles. He would still be a good squad player, but Liverpool need a top midfielder to protect their shaky defence.
This would mean Can could create more opportunities for the forward players as we saw against Dortmund, the former Leverkusen midfielder is capable of getting assists.
Liverpool have the likes of Phillipe Coutinho, Roberto Firmino and Adam Lallana already, but these guys need someone who is going to give these guys the ball.
Can being pushed forward would certainly help in this regard, but he would still need to carry out some defensive duties.
When Coutinho is out of the side, the creativity in Klopp's side significantly weakens. That's why players like Mario Goetze and Yohan Cabaye have been linked in recent months.
The latter is good from set-pieces too, something the Reds have been missing since Steven Gerrard left the club last summer.
Whether the creative midfielder is part of a three-man midfield or behind the striker, he needs to be able to dictate the tempo and ideally be good at set-pieces.
People may argue that Liverpool need a centre forward still, but with Origi thriving up front before his injury, Danny Ings to return, Daniel Sturridge and Firmino all in the ranks, that should be Klopp's last priority.
