Barcelona's Champions League ambitions have suffered a significant setback with the news that winger Raphinha is facing an extended spell on the sidelines. The club confirmed the Brazilian has sustained a right hamstring injury, expected to keep him out for approximately five weeks.

This timeline delivers a brutal blow to Barcelona's European campaign. Raphinha is now set to miss the entire two-legged quarter-final clash against Atletico Madrid. Furthermore, should Barcelona advance, he would also be absent for at least the first leg of the semi-finals, casting doubt on his availability for a potential second leg as well.

Reports indicate the injury occurred during Brazil's recent friendly against France in the United States, with the player having felt discomfort prior to the match. The nature and location of the setback have reportedly left Barcelona's hierarchy frustrated.

Raphinha's absence leaves a major void in Xavi's attack. The 29-year-old has been in electrifying form this season, contributing 19 goals and 7 assists in 31 appearances. His recent two-goal, two-assist masterclass against Newcastle United in the Champions League round of 16 showcased the very threat Barcelona will now be without.

This development could have wider ramifications in the tournament. For instance, Arsenal, who face Sporting CP in their quarter-final, would potentially meet the winner of Barcelona vs. Atletico Madrid. Raphinha's absence would significantly alter the tactical landscape of any such semi-final encounter, removing one of Europe's most in-form wingers from the equation.
