Manchester United defender Eric Bailly insists no player is entitled to a starting place under Jose Mourinho.
Asked if competition was good for the defenders, Bailly told United Review: "It's very important for us, it's important for the team, it's important for the manager, and when it's like that, there is also competition amongst ourselves, so we always have to improve because I don't think anyone is automatically entitled to their position in that team.
Bailly added: "There's a good relationship between Phil and me, and with the other two defenders, Victor Lindelof and Chris Smalling, even though we've not had the chance to play together yet.
"It's fine in my view because there are four of us defenders and everyone is ready to make the most of the opportunities the manager gives us. To defend as well as possible and concede less goals, that's the aim for all of us."
"For me, the aspect that was very important and where I see improvements - and can improve even more, to be honest - is the tactics, as well as the high level of concentration that's required," said Bailly.
"For a young defender it's very important and with this manager I'm positive about the future."
