Julian Alvarez cut short 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 raised concern at the club's base. Spanish reports indicate medical staff are checking his condition. Real Sociedad welcome Atletico this weekend in San Sebastian. If Alvarez is not cleared to play, coach Diego Simeone might need to reshape his attack. No official update has arrived from the club. His status for the match has not been confirmed.
