In that tie, also in the last 16, PSG picked apart Barcelona 4-0 in the first leg but fell to a ridiculous 6-1 defeat in the second leg at the Nou Camp to exit the tournament on away goals.
PSG, who lost the 2020 final to Bayern Munich, return to the site of their remarkable defeat by Barca for this evening’s second leg, looking to move towards this season’s last eight.
Mauricio Pochettino, himself a runner-up in the Champions League in 2019, takes charge of his first game with PSG in the competition, having lost just one of his first 10 matches as head coach at the club since arriving at the start of January.
Barcelona, meanwhile, are in fine form themselves, having won eight straight fixtures across all competitions. Here’s everything you need to know about tonight’s game.
The match will kick off at 8pm GMT this evening at the Nou Camp.
The game will air live on BT Sport 3 HD. Subscribers can also stream it live on the BT Sport website and app.
Barca are without long-term absentees Ansu Fati, Gerard Pique and Philippe Coutinho. Ronald Araujo misses out due to a sprained ankle, and Sergi Roberto is a doubt after sustaining a muscle injury this week. Sergino Dest returns, however.
Former Barca winger Neymar is absent for PSG with an adductor problem, which could also keep him out of the second leg, while another wide option in Angel Di Maria picked up a thigh issue recently. Marco Verratti could miss out due to a knock, and former Barca man Rafinha is suffering from a muscle injury that may prove too much to overcome. Pochettino is also without defenders Colin Dagba, Timothee Pembele and Juan Bernat.
Barcelona: Ter Stegen; Dest, Umtiti, Lenglet, Alba; Busquets, De Jong, Pedri; Dembele, Messi, Griezmann
PSG: Navas; Florenzi, Marquinhos, Kimpembe, Kurzawa; Gueye, Paredes; Kean, Draxler, Mbappe; Icardi
It could be a cagey first leg, with the tie opening up in the reverse fixture in Paris. Barca 1-1 PSG.
