Julian Alvarez stepped away from Atletico Madrid training early 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 say medical staff are checking his condition. Real Sociedad host Atletico this weekend in San Sebastian. If Alvarez is unavailable, coach Diego Simeone might need to reshape his attack. No formal update has been released from the club. His status for the match is still uncertain.
