Liverpool have confirmed defenders Mamadou Sakho and Tiago Ilori have completed their moves to Anfield.
The 23-year-old Sakho, already a France international, arrives from Ligue 1 champions Paris St Germain while 20-year-old Ilori joins from Sporting Lisbon.
Sakho told the club's official website: "I'm delighted to be here. I'd like to thank everyone for the welcome.
"I came here because the project that is in place at Liverpool interests me. I'm really looking forward to playing my first game.
"I know the Liverpool fans are fantastic and while I was in France, it was clear for me to see they are amongst the best in England."
Ilori added: "It feels great being a Liverpool player - coming to the Premier League has always been a dream for me.
