Manchester City midfielder Rodri sustained a groin injury in the 2-1 win over Arsenal in the Premier League, manager Pep Guardiola said. The Spanish international came off in the 88th minute. "Well make a test tonight," Guardiola said Sunday. Rodri has returned to his best form in recent weeks after regaining his full sharpness after ACL and groin injuries. Rodris absence would be a blow to second-placed Citys title hopes. The team is three points behind Arsenal but has a game in hand. "I dont know how long Rodri will be out," Guardiola added, looking ahead to Wednesdays potentially decisive clash with Burnley. The Associated Press contributed to this report.
