Sevilla midfielder Grzegorz Krychowiak suffered a cracked rib during the European Super Cup tie against Barcelona on 13 August, which went to extra time after the Europa League winners came back from being 4-1 down.However, the fightback amounted to nothing as substitute Pedro scored the winner to give Barcelona their first trophy of the season.
Sevilla are confident that it will not be a long-term injury for the Poland international.
A statement read that the player, who was deployed at centre-back, played through the pain and put in a major shift for 120 minutes following an injury crisis in defence for the La Liga club.
"The team effort was titanic and there was one player, Krychowiak, who ended the game bandaged," the club said, as quoted by Goal.
"The Pole was the only player to end the game with a bandage, due to a cracked rib.
"He will be incorporated into training based on his tolerance of the pain," he added.
The news comes as a major blow for Arsenal, who had sent scouts to watch the player, according to The Telegraph, and were preparing a £22m ($34m) bid to bring him to North London. Arsene Wenger, who is a huge fan of the player, has been monitoring him for over 18 months and wants to bring him in as back-up for Francis Coquelin, who has taken an increasingly vital role at the Emirates Stadium over the past nine months.
The injury is likely to delay matters for Arsenal, who have made only one first team signing this summer in the form of Petr Cech, who was not at his best in the Gunners' 2-0 loss to West Ham at home. Arsenal play Crystal Palace on Sunday (16 August) as Wenger's men look to put that loss behind them and go back to winning ways.
