The 22-year-old believes the mixture of youth and experience gives Carlo Ancelotti's squad the perfect balance ahead of some tough fixtures at home and in Europe
Carlo Anceotti's side are unbeaten in Ligue 1, having picked up three wins and three draws, and sit third in the table behind Marseille and Lyon.
Sakho, 22, believes that the only team that can conquer the cash-rich club right now are themselves, and he hopes further good results will continue to swell confidence among les Parisiens.
The French international told reporters: "We have a lot to be optimistic about, because in the team there are plenty of experienced players.
"They'll know how to handle our upcoming matches and help the younger players, like me, to get through them well. Who can beat Paris right now? Maybe Paris…"
"For the moment, we just need to string together the good performances," he added. "That's how we'll build up our confidence."
On the back of their 4-0 win at Bastia at the weekend, PSG face Sochaux this coming Saturday.
