Manchester United forward Anthony Martial could be out for the remainder of the season after picking a knee injury while on international duty.
The Frenchman missed Les Blues' last two World Cup qualifiers last week and could be out for a number of weeks.
Speaking ahead of Man United's Premier League game against Brighton, coach Ole Gunnar Solskjaer was disappointed that the forward's season could now be over.
“Unfortunately, he sprained his knee with France. It’s always when they go away on internationals… you can keep your fingers crossed and hope they come back fit.
"Paul has played in all three games, 30, 60, 90 minutes, so that was a boost for us.
“Losing Anthony for what might be the rest of the season is very disappointing, especially when reports from there [France] was that it wasn’t anything serious but it looks a bad one.”
