Barcelona's squad are preparing for the Champions League game
Iniesta, hurt, did not play in the session and will miss the game
Lionel Messi, who seemed like he might be hurt during the game against Athletic Bilbao at San Mames, trained normally on Sunday ahead of the Champions League game against Olympiakos.
The Argentine is expected to start in Athens, but Gerard Pique will not - the centre-back is suspended and will not make the trip. A problem for Valverde, but Javier Mascherano should be back from his fever to fill in. If not, it might be Thomas Vermaelen, who has overcome a hip problem to return to the squad.
Youth team players Alfaro, Santi Bueno, Samu Araujo and Moisés from Barça B and Iñaki Peña from Juvenil A were called upon to pad out the squad for the session.
