Liverpool boss Rafa Benitez is confident new signings Andrea Dossena and Robbie Keane will prove their class this season.
"They are both players with quality and they are both internationals so I am sure that they will improve. Sometimes a player can come into a team and do well straight away but usually they need time to adjust.
"When we signed Skrtel some people were saying he was not good enough after just one game but we all know of his quality now."
