Marcos Alonso has invited the competition Alex Sandro could bring to Chelsea.
The left-back emerged as surprise regular for Chelsea last season and played an important role in helping the Blues win the title.
However, manager Antonio Conte has demanded that there should be competition for every spot, with Juventus defender Sandro linked with a £70m move to the club.
"I will just keep training, keep improving, keep doing well for the team and keep fighting," he said.
"This is Chelsea. We play in four competitions this year, so many games and competition can only be good for me and for the team."
