The massive Champions League Round of 16 clash has arrived, and for many of the players flying from Paris this will not be the first time they've stepped out onto the turf at the Bernabéu. Seven of the PSG visitors have pasts in La Liga, which adds another sub-plot to what is undoubtedly going to be an intriguing game.
Unai Emery
The Basque coach rose from the Spanish third division (Seguna B) up to La Liga, excelling in his work at Valencia and Sevilla, until he departed for the Parc des Princes.
Alphonse Areola
Loaned out to Villarreal, the goalkeeper flourished as the Spanish side's first choice keeper, returning to Paris rejuvenated, and was handed a spot in the starting XI by Emery.
Dani Alves
The right-back dazzled at Sevilla before stepping into the global spotlight at Barcelona, where he was a part of one of 'Los Cules' best ever spells.
Yuri Berchiche
The left-footed full-back arrived in Paris from Real Sociedad to create competition for Layvin Kurzawa, after establishing himself as a fixture in the La Liga side last season.
Angel Di Maria
The adaptable Argentinian was one of the bastion's of Carlo Ancelotti's Real Madrid side in the season where they achieved the Décima, exhibiting his versatility and unselfishness in the spine of the team.
Lassana Diarra
He arrived in Madrid in the winter transfer window in 2009 as a total unknown but, through hard work and compromise, the midfielder established himself as a benchmark in his position.
Neymar
The most expensive player of all time departed for Paris, leaving Barcelona and La Liga estranged from the brightest prospect in world football.
