Manchester City boss Pep Guardiola says Kalvin Phillips has to "convince" himself and his team-mates he has a future at the club.
Phillips has made just eight substitute Premier League appearances since joining from Leeds United last summer.
The England midfielder had shoulder surgery in September, which limited his availability earlier in the season.
"Players have to earn my confidence - all of them, not just Kalvin," Guardiola said.
Phillips has been linked with a move away from Manchester City but Guardiola said no decisions would be taken now.
"It depends on the players," Guardiola said.
