The Bianconeri boss acknowledges that his side's Champions League future is in doubt after a 2-2 draw with Galatasaray.
The Bianconeri came from behind to take a 2-1 lead in the Group B encounter, but Umut Bulut's 88th-minute equalizer — moments after Fabio Quagliarella's goal had seemingly won the game — ensured that the Turkish outfit left Juventus Stadium with a share of the spoils.
And the Juve coach was left ruing his side's lack of concentration, which means his side now enters its double-header against Real Madrid with just two points from its opening two games.
"You have to pay attention, even if the team has put in all of the effort to overturn the result," Conte told Sky Sport. "Now the path is uphill, but we should not be discouraged. We will have to play to our very maximum in the next four games. If we are good enough then we will progress, but if we do not progress it will be because others were better."
Conte may have to do without Stephan Lichtsteiner and Mirko Vucinic over the coming weeks after both left the field with injuries, and the manager acknowledges he may be restricted without the pair.
"Lichtsteiner and Vucinic have muscle injuries, but I cannot change the system because we don't have the wingers necessary to play in a 4-3-3 except Simone Pepe," he said. "I must always make a decision based on what I have available in the squad. I cannot play Lichtsteiner or Mauricio Isla higher up."
Juve is back in action Sunday when it entertains AC Milan in Serie A, while its next appointment in the Champions League is a trip to Real Madrid on Oct. 23.
