Paris Saint-Germain head coach Thomas Tuchel believes his side are improving all the time, having booked their place in the Champions League last-16.
A convincing 4-1 victory in Belgrade over Red Star confirmed PSG as winners of Group C, with the runaway French league leaders having recovered well from losing their opening group game 3-2 at Liverpool, who edged out Napoli for the runners-up spot.
And Tuchel announced himself pleased with the way his players took to the challenge of a tough section, telling reporters: "It was a difficult group with a lot of quality. It was hard, especially after our first match in Liverpool.
"The team showed they could play together.Now we need to stay humble and have a professional attitude. We are improving and we are hard to beat."
PSG are now priced at 8/1 to win the Champions League, with their best previous showing a run to the semi-finals in the 1994/95 season.
Meanwhile, skipper Thiago Silva challenged his team-mates to continue their good work into the knockout stages of the competition.
He told L'Equipe: "The goal is achieved. I was a little scared this year that we do not go to the round of 16 because it was difficult, but in the difficulty, there are positive things.
"I hope we will continue like this until the end of the season."
Meanwhile, Juventus are 11/2 to win the Champions League, with Real Madrid available at 10/1.
