Sergio Perez expects Esteban Ocon to be an even tougher teammate to beat this year after the pair fought an intense, and at times bitter, battle last year.
Force India goes into the 2018 season attempting to retain its position as best of the rest behind Mercedes, Ferrari and Red Bull but is expecting to face added competition for the position from McLaren and Renault. A clear fourth place finish last year meant squabbling between the two Force India drivers was not too damaging for the team, but Perez says things will be different in 2018.
"The good thing was how we finished last year and how we ended it working together," Perez said when asked to reflect on his relationship with Ocon.
