Barcelona has received a welcome boost with the return of young winger Lamine Yamal to training. Yamal, 18, has been dealing with a persistent groin issue this season, causing him to miss time for the team. Despite his ongoing injury problems, Spain still selected him for the October international break, but his club quickly withdrew him due to concerns.Now, Barcelona has shared a photo on social media showing Yamal back on the training ground, working his way back to full fitness. While this is a positive development for the team, it's worth noting that two other key players, Dani Olmo and Ferran Torres, have suffered injuries while on Spain duty.
