The Barcelona players looked fatigued yesterday. I think the players need rest but it's unfortunate that they don't have that luxury. They have a game again on Sunday. They played on Thursday last week, played again on Sunday, then played another game on Wednesday, and now they have another game on Sunday. That's like 2-3 days intervals between matches.
Another thing is that Barcelona don't have a big squad and most of their players are injured so they have to play with what they have.
We could see that players like Yamal need rest.
Flick is trying to rotate his squad and reduce the intensity of the game so the players can be refreshed a little.
Their next game against Osasuna is going to be more difficult than Getafe because Osasuna is a better team than Getafe. Barcelona needs to be at their best to win that match and they also ned to rotate and rest some important players to prevent injuries and fatigue.
The Newton third law of motion says that a body will continue to be in motion unless acted by an external force, that's exactly what Barcelona display in their last match and all I can say is that those men are now in their defaults settings. It was the same team that played last season, nothing new but they had a good start this season and that wouldn't last because the roller-coaster is going down gradually but if they put more efforts, even though they don't make rainy goals, they can still be winning with this dominance.
Osasuna has lost two matches but that wasn't at home, it was away match and Barcelona hasn't lost any away matches as well, they tend to win more matches at away matches but will Osasuna agrees on this one, I'm not sure because they are more than average players in this league right now unless Barcelona has a strategies they have in mind to kill them coming days.
