Liverpool are on the right road under Jurgen Klopp, but the German must bring silverware to Anfield, according to Graeme Souness.
Liverpool came from behind to beat Crystal Palace 2-1 at Selhurst Park on Saturday to move third in the Premier League, albeit having played two games more than fourth-placed Tottenham Hotspur.
The visitors' win meant Klopp has now picked up 190 points from his first 100 Premier League matches in charge of the club, a record bettered only by Kenny Dalglish, who collected 205.
Overall, there have been plenty of positives since Klopp replaced Brendan Rodgers at Anfield in October 2015, in the view of the former Liverpool boss.
"Lots of plusses, playing a very attractive football, a team that most neutrals would want to watch," Souness - who coached Liverpool from 1991 to 1994 - told Sky Sports.
"But they have to start winning trophies as that is what you are judged on ultimately and that is the only thing that is missing.
"You have to say that whoever is responsible for the players coming in there have done really well.
"There are some fabulous players and Naby Keita is coming in the summer [from RB Leipzig] and he might just give them that extra bit of quality that I think they need in midfield.
They are certainly on the right road, they just need to win a trophy
"I think they need someone in midfield who sees a different picture. The three that they have got in there today (Jordan Henderson, James Milner and Georginio Wijnaldum) - and I include Emre Can in that - are all very good players, all very workmanlike and do a great job for the cause.
"But none of them have got that real magic and maybe he will give them that.
"And a goalkeeper and a Kevin De Bruyne and a David Silva."
Klopp guided Liverpool to the finals of both the League Cup and the Europa League in his debut campaign on Merseyside, only for the Reds to miss out on both trophies.
It is silverware that is currently the only thing missing for Klopp as far as Souness is concerned.

"But I think they are certainly on the right road, they just need to win a trophy," said the Scot, who won the 1992 FA Cup while managing Liverpool.
"And if you win one, then it makes it so much easier going forward because you start to believe in yourself."
