Felipe Melo remains confident that Galatasaray will reach the knockout stages of the Champions League at the expense of his former club Juventus.
The Turkish champions dropped to third spot in Group B this week and know a win will only see them through to the last 16 following their 4-1 defeat against Real Madrid and the Serie A champions' win over Copenhagen.
However, Melo, who joined the Bianconeri from Fiorentina in 2009, has little doubt that his current club Galatasaray will set the record straight on matchday six.
"Juventus are a great team and we will need an exceptional performance," Melo told Radio Onda Cero.
"However, we are confident that we will emerge victorious and reach the knockout stages."
Galatasaray held Juventus to a 2-2 draw in Turin in the reverse fixture in October, with striker Didier Drogba giving the away side the lead before goals from Arturo Vidal and Fabio Quagliarella restored Juve's advantage. Umut Bulut had the final say with a last-minute equaliser.
The Istanbul giants made it to the quarter-finals of the Champions League last term but their progress was halted by Madrid.
