Pablo Sarabia has called on Paris Saint-Germain to "leave aside individualities" ahead of the 2022-23 campaign.
The midfielder spent last season on loan at Portuguese side Sporting Lisbon, where he scored 15 goals in 29 league appearances.
But Sarabia is now back at PSG and preparing to fight for a place in the squad amid the departures of key personnel such as Angel Di Maria and Xavi Simons.
PSG won Ligue 1 last season, their fourth title in five years, but failed once more to bring their first Champions League trophy back to Paris.
They brought in Lionel Messi to try and help them achieve that goal, but a dramatic collapse to Real Madrid at the Bernabeu in the last 16 meant their ultimate goal went unfulfilled again.
Head coach Mauricio Pochettino was sacked at the end of the season, with former Nice boss Christophe Galtier brought in to replace him.
Sarabia has been impressed by the discipline Galtier has brought to the team and wants the whole squad to form a united front.
"I think in any job, discipline and rules are important," Sarabia told AFP.
"It is necessary for a good cohabitation and to form a good group. I think it will be good for everyone.
"You have to build a good group, leave aside individualities because the most important thing is the collective.
"We see it every year, the teams that are the most united are those that end up winning titles."
Sarabia also commented on his own personal performance, and what he can bring to Galtier's team.
The former Sevilla midfielder added: "Right now, I feel that I am in the best period of my career, with a lot of confidence.
"The most important thing for a team is to have 15, 16, 17 players ready to play, at the same level, because there are a lot of matches.
"Everyone is going to be needed, so I'll be ready for that. I think I can bring work, enthusiasm, goals and assists."
