Josko Gvardiol, Nathan Ake and Kyle Walker were all absent from Manchester City training on Monday morning, ahead of Tuesday’s trip to play Real Madrid in the Champions League.
BBC reports that the trio are injury doubts ahead of the game in Spain.
Ake and Walker were already doubts for the Madrid clash after their specific issues during the international break.
Gvadiol joined them on the sidelines after he was substituted during City’s 4-2 win over Crystal Palace last weekend.
City have had their squad stretched thin due to the sheer demand on the players, as they fight to win the Treble again this season.
