With Roma, Doni at first was blocked from first team action by Italian u-21 international Gianluca Curci and was restricted to UEFA Cup games. After impressing in Coppa Italia competition, however, he eventually replaced Curci in goal for Serie A games.

Doni signed for Premier League club Liverpool on 15 July 2011 on free transfer. He was expected to serve as second-choice goalkeeper behind Pepe Reina. As part of the deal, Roma paid Doni €1.5 million net of tax, roughly covering the wage difference between Roma and Liverpool's deal. Due to Reina's red card against Newcastle United in April 2012, Doni won a place in the starting lineup, becoming the first goalkeeper other than Reina to play in a Premier League match for Liverpool since Daniele Padelli on 13 May 2007.
Doni made his Premier League debut for Liverpool on 7 April 2012 in a 1–1 draw against Aston Villa at Anfield.

In his first season at Anfield, Doni made a total of four appearances. 
In the summer of 2012, new manager Brendan Rodgers allowed Doni to return to Brazil temporarily on personal leave. Although he was still included in Liverpool's squad for the 2012–13 season, Due to this personal leave he missed a chance to start while first choice goalkeeper Pepe Reina was injured; Brad Jones played instead.
