Julian Alvarez left Atletico Madrid training ahead of schedule on Saturday. That has put his spot in doubt for the team's La Liga game at Real Sociedad. The forward's early exit sparked worry at the club's training ground. Spanish reports indicate medical staff are evaluating his condition. Real Sociedad welcome Atletico this weekend in San Sebastian. If Alvarez is unavailable, coach Diego Simeone could be forced to change his attack. No official update has come from the club. His status for the match is still uncertain.
