A youth product of Figueirense in Brazil, Santos helped Brazil capture the 2009 FIFA Confederations Cup. He joined EPL team Arsenal from Fenerbache in 2011 and eventually moved to Brazil to play with Gremio followed by Flamengo.

Both Fenerbahce and Besiktas were excluded for their roles in a domestic match-fixing scandal in 2011.

Arsenal were trying to bounce back from a disappointing debut to their domestic season when they crashed 3-1 at home to Villa and endured the wrath of their fans who are growing increasingly impatient with the club's lack of activity in the transfer market.

Arsenal, AC Milan, Schalke and Real Sociedad also join in the playoff round. Ten teams will advance from the playoff round and join 22 clubs which qualified directly for the group stage draw on Aug. 29.

The 30-year-old fell out of favour with Gunners manager Arsene Wenger last year after managing just 23 first-team appearances in 18 months.

Friday's draw is for the third qualifying round but if the full CAS hearing in early August decides to uphold the ban, Fenerbahce's place will be taken by Bursaspor, who finished fourth in the league last season.
