Barcelona's training ground saw a classic rite of passage this Friday as midfielder Frenkie de Jong made his long-awaited return to the group. The Dutch international, sidelined since February with a serious hamstring injury, was welcomed back in traditional fashion: with a 'tunnel of slaps' from his teammates.

This lighthearted hazing ritual, a staple at the Ciutat Esportiva, marks a player's return to full training. For De Jong, it's a significant and positive step in his recovery process under new manager Hansi Flick. After weeks of individual work, rejoining the squad is a crucial milestone.

The timing couldn't be more critical for Barcelona. The club is preparing for a massive Champions League quarter-final clash against Atlético Madrid this week, and having a fully-fit De Jong would be a major boost. His composure and technical quality in midfield are vital assets for the Blaugrana's European ambitions.

While the tunnel of slaps is all in good fun, it underscores the camaraderie and team spirit within the squad. As De Jong works toward full medical clearance, Barcelona fans will be hoping this return to the fold is the first step toward seeing their star midfielder back on the pitch where he belongs.
