Barcelona's Friday morning training session saw the welcome return of the remaining internationals, as covered by the club’s official website, with Gerard Piqué, Sergio Busquets, Pedro Rodríguez and Andrés Iniesta all returning to the fold ahead of Sunday's La Liga clash against manager Luis Enrique's former club, Celta Vigo.
The four Spain internationals were also joined by Argentine duo Lionel Messi and Javier Mascherano, who did warm-up drills and jogged in Thursday's training sessions but participated in their first full session with the group on Friday.
The club continues to be buoyed by the progress of Messi, who was held out of last week's friendlies with the Argentine national team against Paraguay and Ecuador due to a swollen foot that was so painful that he couldn't even put on a pair of boots in the beginning of the tour of the United States.
Messi's completion of Friday's training, without incident, is encouraging for his chances of starting in Sunday evening's match in Balaidos.
However, Luis Enrique will be without Jordi Alba, who was forced to leave the Spanish national team camp early after suffering an injury in their win over Ukraine, and Thomas Vermealen continues to split his time between individual and group drills as the commanding Belgian continues to work his way back from muscle surgery and toward his Barcelona debut.
