PSG get this round of 16 tie underway!
Hello! Welcome to our live text commentary of this UEFA Champions League round of 16 first leg between Barcelona and Paris Saint-Germain at Camp Nou, Barcelona.
Barcelona will remember the last time they met PSG in the Champions League round of 16 very well. Four years ago Barca overturned a 4-0 first-leg defeat with a 6-1 victory to become the first - and so far only - side to qualify with the next round after losing the first leg by four or more goals. It's a memory PSG would no doubt prefer to forget.
PSG are arguably the stronger force these days having narrowly lost the final of this competition last season. While Barca are looking to make it to the Champions League quarter-finals for a 14th consecutive season, then, Ronald Koeman's team will have to be at their best to overcome Mauricio Pochettino's PSG side. Let's do this!
BARCELONA (4-3-3): Marc-Andre ter Stegen; Sergino Dest, Gerard Pique, Clement Lenglet, Jordi Alba; Frenkie de Jong, Sergio Busquets, Pedri; Ousmane Dembele, Lionel Messi (c), Antoine Griezmann.
SUBS: Samuel Umtiti, Junior Firpo, Neto, Miralem Pjanic, Martin Braithwaite, Riqui Puig, Oscar Mingueza, Matheus Fernandes, Trincao, Inaki Pena.
Barca and PSG are out on the Camp Nou pitch now. The two captains Messi and Marquinhos exchange pleasantries, while Koeman and Pochettino share a warm embrace.
These two will meet again at the Parc des Princes in three weeks' time then. Barca have a job on their hands while PSG are firmly in the driving seat in this tie. The Parisians look serious contenders for the trophy once again. That's all for now. Goodbye!
