Messi missed the deadline set by coach Pep Guardiola for his players to return last week and sat out their victory over Real Mallorca.
But Samuel Eto'o joked: "For me, Messi could come the same day of the match. If I were coach he would play absolutely every time."
Barca skipper Carles Puyol also said: "No problem. Leo wanted to take care of some problems but was delayed in Madrid. I repeat, no problem."
