Liverpool boss Brendan Rodgers has set out his plans for the summer market.
Kolo Toure has already arrived from Manchester City, while Celta Vigo striker Iago Aspas should sign this week.
"I'm looking to bring 20 more goals into the team," said Rodgers. "I'm looking at another offensive player to give us a real threat on goal and another attacking midfield player. We definitely need to do that, especially if we're going to put some young ones out on loan to gain experience.
"But it's not easy when you can't make mistakes. We want to keep the acceleration and pushing on, so this is a very important window for us in the summer. We have to do our best to make it right, because the players who need to come in have to be effective right from the off."
