The former Barca youth product was given a less-than-50-percent chance of playing against his former club by Gunners boss Arsene Wenger on Tuesday, after the Spaniard sat out his side's training session to nurse the knee he injured during Saturday's 1-1 draw at Birmingham City.
However, according to Marca, Fabregas has since taken part in a light training routine on Wednesday morning, and is set to participate in the much-anticipated last eight encounter against Pep Guardiola's free-flowing Catalans.
The 22-year-old midfielder - who has netted 18 times in all competitions in 2009/10 - has long been linked with a move back to the Camp Nou, having left Barca's youth ranks to sign for Arsene Wenger's side in 2003.
Fabregas has repeatedly insisted that he is committed to Arsenal's cause as they go in search of a first trophy since the 2005 FA Cup - while admitting that he does dream of returning to his former employers one day in the future.
