Following FC Barcelona's scrappy 2-1 win away at Slavia Praha in the UEFA Champions League on Wednesday night, a Blaugrana star appeared to be annoyed with his teammates.

After Lionel Messi put the visitors ahead inside three minutes, Barca fans would have been looking forward to seeing the back of the net bulge a few more times in the first half.
However, Ernesto Valverde's side took just their 1-0 lead into the break, before Slavia's Jan Boril equalised for the hosts in the 50th minute.
Seven minutes later, the Blaugrana were back in front after an unfortunate own goal from Peter Olayinka, but did not look in control of the Group F encounter.
A few marvellous saves from goalkeeper Marc-Andre ter Stegen kept the Spanish giants ahead, and after the game, the German shot-stopper said he felt the need to have a private chat with a few of his colleagues following their lacklustre performance.
"We did not play at the level we wanted, but thankfully we got the three points, which is the most important thing," he told Movistar+.
"It is necessary to talk about some things. We have to do it between ourselves, I will not say it here, but there are things to improve – a few of them.
"This is an internal matter as well, I don't want to do it here. I would like to talk to those who were on the field first.
"They scored against us right on the first chance of the second half. This can't happen to us, I was quite alone.
"He doesn't do anything special; he takes a pass and it's just ahead of the goal. We have things to improve, that's a tactical thing, that we didn't go back to 100%. That's it, things that happen during a game.
"On a personal level, I always want to be there. If I can help the team, even better. In the first half we had chances against us in which we were not well placed, but these are things that happen."
Barca are now top of Group F with seven points, three points ahead of Inter Milan and Borussia Dortmund, and six points in front of Slavia.
