Barcelona commence their 2020/21 Champions League campaign on Tuesday when they take on Hungarian champions, Ferencvaros.
The fixtures comes a few days after the Catalan side lost their first game of the season in a 1-0 defeat away to Getafe.
Luckily for them, Real Madrid were defeated, too.
The Champions League match is naturally an important one for Barca, but this upcoming weekend they have one of the biggest of the whole season as they take on Madrid in the Clasico.
Will the importance of the Madrid game play on Koeman's mind when it comes to team selection against Ferencvaros?
The answer is probably not, as he will be keen to regain as much momentum as possible following the loss against Getafe. Therefore, we can expect the big hitters like Lionel Messi to play against the Hungarian outfit.
Marc-Andre ter Stegen, Jordi Alba, and Samuel Umtiti are all out injured, though the Frenchman was pictured taking part in full training over the weekend, so shouldn't be too far away from a return.
