Jamie Carragher believes Liverpool need another attacker to complement their front three - and believes Jadon Sancho may be the man.
Sancho is on Liverpool's radar after firmly establishing himself as one of Europe's hottest properties over the last couple of years.
Manchester United , Barcelona and Real Madrid are also monitoring the Borussia Dortmund flier who is set to be a key part of Gareth Southgate's England squad for next summer's Euros.
He returned to form with a fine strike against the Catalan giants for Dortmund in the Champions League on Wednesday night.

And Carragher thinks Sancho could be the man to complete Liverpool's forward line - suggesting the move could come next summer.
He told Viasport: “I think Liverpool still lack one player which is an attacking player to really support the front three and almost make it like a front four.
“At the moment there’s still a big difference when one of the front three don’t play.

“We saw that at the weekend again when Salah was out – that time Alex Oxlade-Chamberlain played in the front three and that didn’t work. We’ve seen [Divock] Origi that doesn’t work.
“Maybe there’s talk of a man in the Bundesliga coming to England from Borussia Dortmund, maybe he’s someone who Liverpool may be looking at in Sancho who a lot of other Premier League clubs are looking at.
“There has been some great signings for Liverpool in the past [in January]. You think of [Virgil] van Dijk, Luis Suarez, Daniel Agger was a great player for Liverpool, Daniel Sturridge is another one.
“I would like to see an attacking player come in someone with a bit more quality, maybe someone who could help them in the coming months going forward.
“I don’t think it’s an area which Klopp really looks at but I would expect it to be a really big summer for Liverpool especially considering they didn’t sign anyone last summer.”
