Nice midfielder Jean Michael Seri missed their game on Saturday.
The Barcelona target was not been included in the Nice squad for Saturday's game against Amiens.
Sport says Seri was disappointed by the collapse of his move to Barcelona.
It's affected him deeply that a four-year deal with Barça fell through at the last minute. With that context, his coach Lucien Favre preferred not to call him up for this weekend's game despite his importance to the team.
