Clash of Barca and Manchester United underlines soaring revivals

Barcelona host Manchester United Thursday in a match-up which has twice graced the Champions League final but this week has the relative ignominy of taking place in the Europa League play-off round.

The Catalans crashed out of Europe's premier competition at the first hurdle, while Manchester United finished runners up in their Europa League group, leading their paths to cross.

Despite the tie's diminished stature, both fallen giants are on the rise and among the teams in the best form across the continent.

Barcelona and Manchester United are both building under exciting coaches in Erik ten Hag and Xavi Hernandez and aiming to return to Europe's elite imminently. 

The teams last met in 2019 when United's harsh decline in the barren decade after Sir Alex Ferguson's reign was in full swing and Barcelona's deep slide was about to begin. 

Five-time Champions League winners Barca won the quarter-final clash 4-0 on aggregate, but their only player from their starting line-ups then likely to face United at Camp Nou is goalkeeper Marc-Andre ter Stegen. 

Barcelona have gone through a profound squad renewal since -- with their spending last summer increasing the criticism they received after dropping into the Europa League. 

In Robert Lewandowski the Catalans signed a lethal striker, while Jules Kounde and Andreas Christensen have established themselves as key elements of Europe's best defence. 

Barcelona have conceded just seven goals in La Liga this season, keeping 16 clean sheets from 21 matches, and Xavi's side are unbeaten in 16 games across all competitions. 

The coach, who starred for Barcelona in midfield in their 2009 and 2011 Champions League final victories over Ferguson’s Red Devils, is returning his side to their former glory.
