Thiago Silva has claimed that his Paris Saint-Germain teammates are playing at a higher level compared to last season.
Despite completing the clean sweep of trophies in the 2014-15 season, Laurent Blanc's side had to overcome a title challenge from Lyon in the second half of last year's campaign.
However, PSG currently have a 15-point lead at the top of Ligue 1, which the Brazilian defender is putting down to a more dedicated effort from every player.
"On the pitch, everyone realises we always have to be at 100%. Last season, we were often 80% and that is not enough to win a game," Thiago Silva told PSG's official website.
"We were champions because the team had many qualities. This season, everyone is playing at 100% and that is why we have made this start to the campaign.
"But we must continue to work together, together we are much stronger. I am always telling that to my teammates."
PSG will look to extend their lead at the top of the table when they face Lyon this Sunday at the Parc des Princes.
