Celtic's on-loan midfielder Landry N'Guemo believes his team-mates will need to be perfect to regain the SPL title.
The Bhoys are currently 10 points adrift of their arch-rivals Rangers after dropping two more points in their thrilling 4-4 draw with Aberdeen.
Celtic are left with a mountain to climb to overtake Gers, although they do have two more head-to-head SPL meetings before the end of the season.
On-loan Nancy ace N'Guemo believes Tony Mowbray's squad remain united and that everyone believes they can be perfect for the rest of the season.
"The spirit is very good here and I'm very happy to play in this team," explained N'Guemo.
"We are 10 points behind the leaders and we have to really fight in order to go to the top of the table.
"We cannot afford any more mistakes, we must win all 13 games.
"We have a good team, we can win all these matches."
